Question: Error "The value for one of the HTTP headers is not in the correct format" when using the storage emulator

Solution:
This scenario typically occurs if you install and use the latest version of the Storage Client
Library without updating the storage emulator. You should either install the latest version of the storage emulator or use cloud storage instead of the emulator for development and testing.


Question:
I am experiencing unexpected delays in message delivery on a
 queue

Solution:
1. Verify that the application is successfully adding the messages to the queue. Check that the application is not retrying the AddMessage method several times before succeeding.

2. Verify there is no clock skew between the worker role that adds the message to the queue and the worker role that reads the message from the queue. A clock skew makes it appear as if there is a delay in processing.

3. Check if the worker role that reads the messages from the queue is failing. If a queue client calls the GetMessage method but fails to respond with an acknowledgment, the message will remain invisible on the queue until the invisibilityTimeout period expires. At this point, the message becomes available for processing again.

4. Check if the queue length is growing over time. This can occur if you don't have sufficient workers available to process all of the messages that other workers are placing in the queue. Also, check the metrics to see if delete requests are failing and the dequeue count on messages, which might indicate repeated failed attempts to delete the message.

5. Examine the Storage logs for any queue operations that have higher than expected E2ELatency and ServerLatency values over a longer period of time than usual.


Question: Root not redirecting to the index document

Solution:
When you enable static website hosting on Azure Storage, you need to specify the name of the index document that will be served when a user requests the root URL of your website. For example, if you set the index document name to "index.html", then your website will display the content of that file when someone visits https://yourwebsite.zxx.web.core.windows.net/.

However, sometimes you may find that the root URL does not redirect to the index document, and instead shows a blank page or an error message. This could happen for several reasons:

Ensure the name and extension as set in the file name on the portal are the exact same of the file in the $web container, including case sensitivity. File names along with extensions are case sensitive. Even though this is served over HTTP, index.html != Index.html for Static Websites.
Ensure that the index document exists in the $web container and has a valid content type. You can check this by using Azure Portal, Azure CLI, or Azure Storage Explorer.
Ensure that there are no other files or folders in the $web container that have the same name as the index document. For example, if you have a folder named "index.html" in the $web container, it will conflict with the index document and prevent it from being served.


Question: Unable to acquire token, tenant is filtered out

Solution:
Sometimes you may see an error message that says a token can't be acquired because a tenant
 is filtered out. This means you're trying to access a resource that's in a tenant you filtered out. To include the tenant, go to the Account Panel. Make sure the checkbox for the tenant specified in the error is selected. For more information on filtering tenants in Storage Explorer, see Managing accounts.


Question: Slow performance when unzipping files in SMB file shares

Solution:
Depending on the exact compression method and unzip operation used, decompression operations may perform more slowly on an Azure file share than on your local disk. This is often because unzipping tools perform a number of metadata operations in the process of performing
the decompression of a compressed archive. For the best performance, we recommend copying the compressed archive from the Azure file share to your local disk, unzipping there, and then using a copy tool such as Robocopy (or AzCopy) to copy back to the Azure file share. Using a copy tool like Robocopy can compensate for the decreased performance of metadata operations in Azure Files relative to your local disk by using multiple threads to copy data in parallel.


Question: How to change the Lease state of Azure Blob to Available

Solution:
A lease can only be cleanly released by using the lease id that was returned during the original lease operation.
You can change the lease state to available manually by leasing and releasing the blob using Azure CLI, or any other SDK.


Question:
I am trying to upload a binary file (a blob for an excel file, actually) to
my storage account but the client fails to authenticate under the error message: 403 (Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.)

Solution:
This message you'll get if your SAS Token expired. If this is the case just create a new
version of the secret using a SAS token with a longer duration.


Question: Unable to provision a network drive as Server Endpoint in Azure File Sync. Shows Server endpoint creation fails, with this error: "MgmtServerJobFailed" (Error code: -2147024894 or 0x80070002)

Solution:
This error occurs if the server endpoint path specified is not valid. Verify the
server endpoint path specified is a locally attached NTFS volume. Note, Azure File Sync does not support mapped drives as a server endpoint path.


Question:
copy file from local machine to Azure Blob not successful. Error INFO: Any
empty folders will not be processed, because source and/or destination doesn't have full folder support

Solution: As indicated in the error INFO: Any empty folders will not be processed by azcopy, Just create a file inside the source directory and try the azcopy command again.


Question: Unable to trigger azure function though service bus queue

Solution:
That's an indication that your Function is not activated. And if it's not activated while a message is found on the queue, the potential issue would be Function configuration.
You need to specify connection string and queue name. If there is no connectivity exception, that tells me the connection string is working, Just validate is the right namespace connection. Then, check if the queue the Function is configured with is the right queue.


Question: What are the possible ways available to Scale Out/In VMs based on number of outstanding requests of Azure storage queue?

Solution: You can use Metric alerts (assuming that number of requests is the same as Queue Message Count or some other metric) to create such alerts that are attached to action group that has link to automation service like Azure Automation runbook or Azure Function. The logic of those services will be code that scales out/in.


Question: I am not able to create a folder under the blob container

Solution:
From the azure portal you can go inside your container —> click on Upload —> in
the Advanced section go to Upload to Folder and provide a folder name —> browse the file to upload —> click on Upload button You should see a folder getting created.


Question: Lifecycle policy moving from cool to hot not working

Solution:
The policy you have defined is moving the blob from "Hot" to "Cool" after 2 days of modification. If you want to move the blob from "Cool" to "Hot" after it gets modified, you need to change the action in the first rule to "tierToHot" instead of "tierToCool".

Also, you have defined the second rule to enable auto-tiering to "Hot" from "Cool" based on last access time. However, this rule will only take effect if the blob is currently in "Cool" and then accessed. It will not move the blob from "Cool" to "Hot" immediately after it gets modified.

You can try adding a new rule that moves the blob from "Cool" to "Hot" based on last modified time.


Question: Missing error details for some failures in Insights for storage account

Solution:
You need to create a diagnostic setting to collect resource logs for blobs. Once
the diagnostic setting is created you can investigate the logs. If you are using Log Analytics this can be done directly from Logs (preview) under monitoring.


Question:
Unable to create Storage account; error loading the Creation page of
Storage account

Solution:
1. Disable if there is adblock and clear all your cookies restart the browser and relogin into azure portal
2. If you are using chrome or firefox try opening azure portal from edge browser and create resource
3. Open InPrivate session from your browser and login into the portal


Question:
how to set access permissions for azure blob storage container at folder
(prefix) level

Solution:
1. If you use ADLS (HNS) I believe you can set an ACL on a folder . For existing storage account blob container, you would need to copy into an HNS enabled storage account (current situation)
2. You could produce a SAS for a blob container or for individual blobs(SAS token can be used to restrict access to either an entire blob container or an individual blob. This is because a folder in blob storage is virtual and not a real folder.).


Question: Error trying to delete container in storage account

Solution:
If you are getting the "Failed to delete 1 out of 1 container(s) The request uri is
invalid " Please first try to hard refresh the Screen/Browser page. There may be some interface issue.


Question:
Is there a way to enable Soft delete on Storage Account through custom
policy

Solution:
Yes, you can turn on soft deletion for storage accounts through a policy. You can do this through the portal/powershell/azure cli/template options.
You can "[s]pecify a retention period between 1 and 365 days." PowerShell (7 days)


Question: How to stream blobs to Azure Blob Storage with Node.js

Solution:
Navigate to your storage account in the Azure Portal and copy the account name
and key (under Settings > Access keys) into the .env.example file. Save the file and then rename it from .env.example to .env.

Question:
I cannot create or delete a web app due to a permission error. What the
 permissions do I need to create or delete a web app?

Solution: You would need minimum Contributor access on the Resource Group to deploy App Services. If you have Contributor access only on App Service Plan and web app, it won't allow you to create the app service in the Resource Group.


Question: How do I restore a deleted web app or a deleted App Service Plan?

Solution: If the web app was deleted within the last 30 days, you can restore it using Restore-AzDeletedWebApp.


Question:
Which SQL cloud database deployment options are
available?

Solution:
Azure SQL Database is available as a single database with
its own set of resources managed via a logical server,and
 as a pooled database in an elastic pool, with a shared set of resources managed through a logical server. In general, elastic pools are designed for a typical software-as-a-service (SaaS) application pattern, with one database per custtomer or tenant. With pools, you manage the collective performance, and the databases scale up or down automatically.


Question:
Error message: Conversion failed when converting from a
character string to uniqueidentifier

Solution:
In the copy activity sink, under PolyBase settings, set the use type
default option to false.


Question:
Cannot open database "master" requested by the login. The login

excessive transaction log space usage

Solution:
The issue can occur in any DML operation such as insert, update, or
delete. Review the transaction to avoid unnecessary writes. Try to reduce the number of rows that are operated on immediately by implementing batching or splitting into multiple smaller transactions.


Question: Error 5: Cannot connect to < servername >

Solution:
To resolve this issue, make sure that port 1433 is open for outbound
connections on all firewalls between the client and the internet.


Question:
Error 40551: The session has been terminated because of
excessive tempdb usage

Solution:
1. Change the queries to reduce temporary table space usage.
2. Drop temporary objects after they're no longer needed.
3. Truncate tables or remove unused tables.

Specified elastic pool does not exist in the specified server.

Solution: Provide a valid elastic pool name.


Question: Getting error as Elastic pool does not support service tier '%ls'. Specified service tier is not supported for elastic pool provisioning.

Solution:
Provide the correct edition or leave service tier blank to use the default
service tier.


Question:
Error Code:40860
Elastic pool '%ls' and service objective '%ls' combination is invalid.

Solution: Specify correct combination of elastic pool and service tier.


Question:
Error Code:40877
I cannot able to delete elastic pool

Solution: Remove databases from the elastic pool in order to delete it.


Question:
Error Code:40857
Elastic pool not found for server: '%ls', elastic pool name: '%ls'.

Solution: Provide a valid elastic pool name.


Question: Error code: 2056 - SqlInfoValidationFailed

Solution:
Make sure to change the target Azure SQL Database collation to the same
 as the source SQL Server database. Azure SQL Database uses SQL_Latin1_General_CP1_CI_AS collation by default, in case your source SQL Server database uses a different collation you might need to re-create or select a different target database whose collation matches.


Question: Not able to decrease the storage limit of the elastic pool

Solution:
Consider reducing the storage usage of individual databases in the
elastic pool or remove databases from the pool in order to reduce its DTUs or storage limit.


Question:
c# error when connect to mysql "Object cannot be cast from
DBNull to other types" (mariadb 10.3)

Solution:
 when a column value is null, the object DBNull is returned rather than a
typed value. You must first test that the column value is not null via the api before accessing as the desired type.


Question: Error code: AzureTableDuplicateColumnsFromSource

Solution: Double-check and fix the source columns, as necessary.


Question: Error code: MongoDbUnsupportedUuidType

Solution: In the MongoDB connection string, add the uuidRepresentation=standard option.


Question: Error message: Request rate is large in Azure CosmosDB

Solution:
Try either of the following two solutions:
1. Increase the container RUs number to a greater value in Azure Cosmos DB. This solution will improve the copy activity performance, but it will incur more cost in Azure Cosmos DB.
2. Decrease writeBatchSize to a lesser value, such as 1000, and decrease parallelCopies to a lesser value, such as 1. This solution will reduce copy run performance, but it won't incur more cost in Azure Cosmos DB.


Question: Error code: SqlOpenConnectionTimeout

Solution:
 Retry the operation to update the linked service connection string with
a larger connection timeout value.


Question: Error code: SqlAutoCreateTableTypeMapFailed

Solution:
Update the column type in mappings, or manually create the sink table
in the target server.


Question: Error code: SqlParallelFailedToDetectPartitionColumn

Solution:
Check the table to make sure that a primary key or a unique index is
created.


Question: Client can't reach an Azure Kubernetes Service (AKS) cluster's API

Solution:
Ensure that your client's IP address is within the ranges authorized by the cluster's API server:

1. Find your local IP address. For information on how to find it on Windows and Linux, see How to find my IP.

2. Update the range that's authorized by the API server by using the az aks update command in Azure CLI. Authorize your client's IP address.


Question:
when I try to upgrade an Azure Kubernetes Service (AKS) cluster getting
error as "PodDrainFailure"

Solution:
1. Adjust the PDB to enable pod draining. Generally, The allowed disruption is controlled by the Min Available / Max unavailable or Running pods / Replicas parameter. You can modify the Min Available / Max unavailable parameter at the PDB level or increase the number of Running pods / Replicas to push the Allowed Disruption value to 1 or greater.
2.Try again to upgrade the AKS cluster to the same version that you tried to upgrade to previously. This process will trigger a reconciliation.


Question:
 AKS cluster upgrade fails, and getting "PublicIPCountLimitReached" as
error message

Solution:
To raise the limit or quota for your subscription, go to the Azure portal, file a
Service and subscription limits (quotas) support ticket, and set the quota type to Networking.

After the quota change takes effect, try to upgrade the cluster to the same version that you previously tried to upgrade to. This process will trigger a reconciliation.


Question: "SubnetIsFull" error code during an AKS cluster upgrade

Solution:
Reduce the cluster nodes to reserve IP addresses for the upgrade.

If scaling down isn't an option, and your virtual network CIDR has enough IP addresses, try to add a node pool that has a unique subnet:

1. Add a new user node pool in the virtual network on a larger subnet.
2. Switch the original node pool to a system node pool type.
3. Scale up the user node pool.
4. Scale down the original node pool.


Question:
Failed to upgrade or scale Azure Kubernetes Service cluster due to missing
Log Analytics workspace

Solution:
If it has been more than 14 days since the workspace was deleted, disable monitoring on the AKS cluster and then run the upgrade or scale operation again.

To disable monitoring on the AKS cluster, run the following command:

az aks disable-addons -a monitoring -g <clusterRG> -n <clusterName>
If the same error occurs while disabling the monitoring add-on, recreate the missing Log Analytics workspace and then run the upgrade or scale operation again.


Question:
Upgrades to Kubernetes 1.16 fail when node labels have a kubernetes.io
prefix

Solution:
To mitigate this issue:

Upgrade your cluster control plane to 1.16 or later.
Add a new node pool on 1.16 or higher without the unsupported kubernetes.io labels.
Delete the older node pool.


Question:
CannotDeleteLoadBalancerWithPrivateLinkService or
PrivateLinkServiceWithPrivateEndpointConnectionsCannotBeDeleted error code

Solution:
Make sure that the private link service isn't associated with any private endpoint
 connections. Delete all private endpoint connections before you delete the private link service.


Question:
PublicIPAddressCannotBeDeleted, InUseSubnetCannotBeDeleted, or
InUseNetworkSecurityGroupCannotBeDeleted error code

Solution:
1. Remove all public IP addresses that are associated with Azure Load Balancer and the resource that's used by the subnet. For more information, see View, modify settings for, or delete a public IP address.

2. In the load balancer, remove the rules for Load Balance rules, Health probes, and Backend pools.

3. For the NSG and subnet, remove all associated rules.


Question:
when I try to delete a Microsoft Azure Kubernetes Service (AKS) cluster
getting error as InUseRouteTableCannotBeDeleted error code

Solution: Remove the associated subnet in the route table.


Question:
When I tried to delete an AKS cluster while the virtual machine scale set was still using the associated public IP address or network security group (NSG) getting LoadBalancerInUseByVirtualMachineScaleSet or
NetworkSecurityGroupInUseByVirtualMachineScaleSet error code

Solution:
Remove all public IP addresses that are associated with the subnet, and remove
the NSG that's used by the subnet.


Question:
when I try to delete a Microsoft Azure Kubernetes Service (AKS) getting
clusterRequestDisallowedByPolicy error(for cluster deletions)

Solution:
Verify that you have permission to make any changes to policy services. If you
don't have permission, find someone who has access so that they can make the necessary changes. Also, check the policy name that's causing the problem, and then temporarily deny that rule so that you (or someone who has permission) can do the delete operation.


Question:
Getting error asTooManyRequestsReceived or
SubscriptionRequestsThrottled when I try to delete a Microsoft Azure Kubernetes Service (AKS) cluster

Solution:
The HTTP response includes a Retry-After value. This specifies the number of
seconds that your application should wait (or sleep) before it sends the next request. If you send a request before the retry value has elapsed, your request isn't processed, and a new retry value is returned


Question:
I get an "insufficientSubnetSize" error when I deploy an AKS cluster that
uses advanced networking

Solution:
Because you can't update an existing subnet's CIDR range, you must have permission to create a new subnet to resolve this issue. Follow these steps:

1. Rebuild a new subnet that has a larger CIDR range that's sufficient for operation goals.

2.Create a new subnet that has a new non-overlapping range.

3.Create a new node pool on the new subnet.

4. Drain pods from the old node pool that resides in the old subnet that will be replaced.

5.Delete the old subnet and old node pool.


Question: Cluster autoscaler fails to scale with "failed to fix node group sizes" error

Solution: To get out of this state, disable and re-enable the cluster autoscaler.


Question: Node Not Ready failures that are followed by recoveries error

Solution:
To prevent this issue from occurring in the future, take one or more of the following actions:

1. Make sure that your service tier is fully paid for.
2. Reduce the number of watch and get requests to the API server.
3. Replace the node pool with a healthy node pool.


Question: Can't view resources in Kubernetes resource viewer in Azure portal

Solution:
Make sure that when you run the az aks create or az aks update command in
Azure CLI, the --api-server-authorized-ip-ranges parameter includes access for the local client computer to the IP addresses or IP address ranges from which the portal is being browsed.


Question: Getting an error when I try to upgrade or scale a Microsoft Azure Kubernetes Service (AKS) cluster

Solution:
To resolve these scenarios, follow these steps:

1. Scale your cluster back to a stable goal state within the quota.

2. Request an increase in your resource quota.

3. Try to scale up again beyond the initial quota limits.

4. Retry the original operation. This second operation should bring your cluster to a successful state.


Question: Insufficient subnet size error while deploying an AKS cluster with advanced networking

Solution:
Create new subnets. Because you can't update an existing subnet's CIDR range, you'll need to be granted the permission to create a new subnet.

Rebuild a new subnet with a larger CIDR range that's sufficient for operation goals by following these steps:

1. Create a new subnet with a larger, non-overlapping range.

2. Create a new node pool on the new subnet.

3. Drain the pods from the old node pool that resides in the old subnet.

4. Delete the old subnet and old node pool.


Question: Missing or invalid service principal when creating an AKS cluster

Solution:
Make sure that there's a valid, findable service principal. To do this, use one of the following methods:

During cluster creation, use an existing service principal that has already propagated across regions to pass into AKS.

If you use automation scripts, add time delays between service principal creation and AKS cluster creation.

If you use the Azure portal, return to the cluster settings after you try to create the cluster, and then retry the validation page after a few minutes.


Question:
when I am  creating an AKS cluster getting errors after restricting egress
traffic in AKS

Solution:
Verify that your configuration doesn't conflict with any of the required or optionally recommended settings for the following items:

1. Outbound ports
2. Network rules
3. Fully qualified domain names (FQDNs)
4. Application rules


Question:
Error: TCP time-outs when kubectl or other third-party tools connect to the
 API server

Solution:
Make sure the nodes that host this pod aren't overly utilized or under stress.
Consider moving the nodes to their own system node pool.


Question: How can I identify how and when key vaults are accessed?

Solution:
After you create one or more key vaults, you'll likely want to monitor how and
when your key vaults are accessed, and by whom. You can do monitoring by enabling logging for Azure Key Vault


Question:
How can I monitor vault availability, service latency periods or other
performance metrics for key vault?

Solution:
As you start to scale your service, the number of requests sent to your key vault
will rise. Such demand has a potential to increase the latency of your requests and in extreme cases, cause your requests to be throttled which will degrade the performance of your service. You can monitor key vault performance metrics and get alerted for specific thresholds


Question: I'm not able to modify access policy, how can it be enabled?

Solution:
The user needs to have sufficient Azure AD permissions to modify access policy.
In this case, the user would need to have higher contributor role.


Question: How can I give the AD group access to the key vault?

Solution:
Give the AD group permissions to your key vault using the Azure CLI az keyvault set-policy command, or the Azure PowerShell Set-AzKeyVaultAccessPolicy cmdlet.

The application also needs at least one Identity and Access Management (IAM) role assigned to the key vault. Otherwise it will not be able to log in and will fail with insufficient rights to access the subscription. Azure AD Groups with Managed Identities may require up to eight hours to refresh tokens and become effective.


Question: Unable to assign a role using a service principal with Azure CLI

Solution:
There are two ways to potentially resolve this error. The first way is to assign the Directory Readers role to the service principal so that it can read data in the directory.

The second way to resolve this error is to create the role assignment by using the --assignee-object-id parameter instead of --assignee. By using --assignee-object-id, Azure CLI will skip the Azure AD lookup. You'll need to get the object ID of the user, group, or application that you want to assign the role to.


Question:
ClientCertificateCredential authentication issueClient assertion contains
an invalid signature.

Solution: Ensure the specified certificate has been uploaded to the AAD application registration.


Question:
ManagedIdentityCredential authentication unavailable, no managed
identity endpoint found

Solution:
Ensure the managed identity has been properly configured on the App Service.
Verify the App Service environment is properly configured and the managed identity endpoint is available.


Question: Deleted or rejected private end point still shows Aprroved in ADF

Solution:
You should delete the managed private end point in ADF once existing private
 endpoints are rejected/deleted from source/sink datasets.


Question: Connection error in public endpoint

Solution:
1. Having private endpoint enabled on the source and also the sink side when using the Managed VNet IR.
2. If you still want to use the public endpoint, you can switch to public IR only instead of using the Managed VNet IR for the source and the sink. Even if you switch back to public IR, the service may still use the Managed VNet IR if the Managed VNet IR is still there.


Question: Not able to use self-hosted IR to bridge two on-premises datastores

Solution:
Install drivers for both the source and destination datastores on the destination IR, and make sure that it can access the source datastore.

If the traffic can't pass through the network between two datastores (for example, they're configured in two virtual networks), you might not finish copying in one activity even with the IR installed. If you can't finish copying in a single activity, you can create two copy activities with two IRs, each in a VENT:

1.Copy one IR from datastore 1 to Azure Blob Storage
2. Copy another IR from Azure Blob Storage to datastore 2.
This solution could simulate the requirement to use the IR to create a bridge that connects two disconnected datastores.


Question: Unable to register the self-hosted IR

Solution: Use localhost IP address 127.0.0.1 to host the file and resolve the issue.


Question: I can sign in to  Azure portal, but I see the error, No subscriptions found

Solution:
To fix this issue:

1. Verify that the correct Azure directory is selected by selecting your account at the top-right corner.
2. If the correct Azure directory is selected, but you still receive the error message, have your account added as an Owner.


Question: How do I check my current consumption level?

Solution: Azure customers can view their current usage levels in Cost Management


Question: Unable to remove a credit card from a saved billing payment method

Solution:
By design, you can't remove a credit card from the active subscription.

If an existing card has to be deleted, one of the following actions is required:

1. A new card must be added to the subscription so that the old payment instrument can be successfully deleted.
2. You can cancel the subscription to delete the subscription permanently and then remove the card.


Question: VisualStudioCredential authentication issue: Failed To Read Credentials

Solution:
1. In Visual Studio select the Tools > Options menu to launch the Options dialog.
2. Navigate to the Azure Service Authentication options to sign in with your Azure Active Directory account.
3. If you already had logged in to your account, try logging out and logging in again as that will repopulate the cache and potentially mitigate the error you're getting.


Question: AzureCliCredential authentication issue:Azure CLI not installed

Solution:
1. Ensure the Azure CLI is properly installed.
2. Validate the installation location has been added to the PATH environment variable.


Question:
RequestFailedException raised from the client with a status code of 401 or
403

Solution:
1. Enable logging to determine which credential in the chain returned the authenticating token.
2. In the case a credential other than the expected is returning a token, bypass this by either signing out of the corresponding development tool, or excluding the credential with the ExcludeXXXCredential property in the DefaultAzureCredentialOptions
3. Ensure that the correct role is assigned to the account being used. For example, a service specific role rather than the subscription Owner role.


Question: UsernamePasswordCredential authentication Error Code: AADSTS50126

Solution: Ensure the username and password provided when constructing the credential are valid.


Question:
CredentialUnavailableException: The requested identity hasn't been
assigned to this resource.

Solution:
If using a user assigned identity, ensure the specified clientId is correct.
If using a system assigned identity, make sure it has been enabled properly.


Question:
CredentialUnavailableException: ManagedIdentityCredential
authentication unavailable.

Solution:
Ensure the managed identity has been properly configured on the App Service.

Verify the App Service environment is properly configured and the managed identity endpoint is available

Question: Azure ML pipeline run failed with status: '%amlPipelineRunStatus;'. Azure ML pipeline run Id: '%amlPipelineRunId;'. Please check in Azure Machine Learning for more error logs.

Solution: Check Azure Machine Learning for more error logs, then fix the ML pipeline.


Question: Unable to pass data to PipelineData directory

Solution:
Ensure you have created a directory in the script that corresponds to where
your pipeline expects the step output data. In most cases, an input argument will define the output directory, and then you create the directory explicitly. Use os.makedirs(args.output_dir, exist_ok=True) to create the output directory.


Question: Pipeline is rerunning unnecessarily

Solution:
To ensure that steps only rerun when their underlying data or scripts change,
decouple your source-code directories for each step. If you use the same source directory for multiple steps, you may experience unnecessary reruns. Use the source_directory parameter on a pipeline step object to point to your isolated directory for that step, and ensure you aren't using the same source_directory path for multiple steps.


Question: Pipeline not reusing steps

Solution:
Step reuse is enabled by default, but ensure you haven't disabled it in a
pipeline step. If reuse is disabled, the allow_reuse parameter in the step will be set to False.


Question:
I am getting the following error: ModuleNotFoundError: No module
named 'azureml.train' Whenever I try to import the HyperDriveConfig module: from azureml.train.hyperdrive import HyperDriveConfig.

Solution:
The azureml-train package has been deprecated already and might not
receive future updates and removed from the distribution altogether. Please use azureml-train-core instead.


Question:
ModuleNotFoundError: No module named 'azureml' even after
installation

Solution:
To resolve the issue, Please try installing on a notebook by adding % at the
 beginning of pip install command.


Question:
I am using Azure ML for real-time machine learning. I have installed
the Kafka server, but I am having a connection issue when trying to create a topic. I received the following warning: WARN [AdminClient clientId=adminclient-1] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient).

Solution:
1. Verify that the Kafka broker is running: You can check if the Kafka broker is running by using the following command in a new terminal window: ./kafka_2.13-3.3.2/bin/kafka-server-start.sh ./kafka_2.13-3.3.2/config/server.properties
2. Verify that the address and port are correct: Make sure that the address and port specified in the bootstrap-server parameter are correct and that there are no firewall or network configuration issues preventing you from connecting to the broker.
3. Check the Kafka logs for errors: Check the Kafka logs to see if there are any error messages that could help identify the issue. You can find the Kafka logs in the logs directory of your Kafka installation.
4.Try using a different topic name: It's possible that the topic name you're using is already in use or is invalid. Try using a different topic name to see if that resolves the issue


Question: In Azure ML studio deploy option is not there

Solution:
In Azure Machine Learning Studio, the ability to deploy a model is only available in the paid tiers of the service. If you are using a trial account, you may not have access to the deploy functionality.

To deploy a model in Azure Machine Learning Studio, you will need to upgrade to a paid subscription. The deploy functionality is available in the Standard and Enterprise tiers of the service.

Once you have upgraded your subscription, you can follow these steps to deploy your trained model:

Open the Azure Machine Learning Studio and navigate to your workspace.

Navigate to the "Models" tab and select the trained model you want to deploy.

Click on the "Deploy" button and select the deployment target, such as Azure Kubernetes Service (AKS) or Azure Container Instances (ACI).

Configure the deployment settings, such as the number of nodes and the CPU and memory settings.

Click on the "Deploy" button to start the deployment process.

Once the deployment is complete, you can test the deployed model by sending requests to the endpoint.


Question: can I use prebuilt component in custom pipeline mode?

Solution:
Classic prebuilt components provides prebuilt components majorly for data processing and traditional machine learning tasks like regression and classification. This type of component continues to be supported but will not have any new components added.

Custom components allow you to provide your own code as a component. It supports sharing across workspaces and seamless authoring across Studio, CLI, and SDK interfaces.


Question:
Azure Machine Learning - running code in curated environement
gives ModuleNotFoundError: No module named 'azure.ai'

Solution:
You can try to upgrade pip and then install the azure package using these commands:
pip install --upgrade pip
pip install azure-ai-ml


Question:
How to solve an error in model profiling where it is not recognizing
the profile attribute provided by model library?

Solution:
Here are a few steps to resolve this error:

1. Check the library documentation: Make sure that the library you are using to profile the model has a profile attribute and that you are using it correctly.
2. Verify that you have imported the correct library: Check if you have imported the correct library and that the Model class you are using is the one from the library you intended to use.
3. Rename your custom class: If you have a custom Model class with the same name as the one from the library, consider renaming your custom class to avoid any name collisions.


Question:
How to access the data used during the azure automl pipeline
training?

Solution:
You can access the data that was used during the training of an Azure AutoML
 model by using the TrainingData property of the Model object in the Azure Machine Learning SDK.


Question:
Can i run multiple jobs/experiments on a single node using
Compute Cluster ?

Solution:
Use Azure Batch as the compute target in AzureML. With Azure Batch, you can
create a pool of compute nodes and run multiple jobs/experiments concurrently on those nodes. Azure Batch automatically manages the allocation of resources to each job/experiment, so you don't need to worry about dividing your tasks into mini batches.


Question: How To Connect To Managed Instance from Machine Learning Studio

Solution:
To connect to an Azure SQL Database from Azure Machine Learning studio, you need to follow these steps:

1. Create an Azure SQL Database and make sure that it is accessible from your Azure Machine Learning workspace.
2. In Azure Machine Learning studio, go to the Data tab and click on the +New button.
3. Select the SQL Database option and provide the necessary details, such as the server name, database name, and authentication method.
4. Click on the Connect button to establish a connection to the Azure SQL Database.
5. Once the connection is established, you can use the SQL Database as a data source for your machine learning models in Azure Machine Learning studio.


Question:
I tried to create a bucket but received the following error:

409 Conflict. Sorry, that name is not available. Please try a different one.

Solution:
The bucket name you tried to use (e.g. gs://cats or gs://dogs) is
already taken. Cloud Storage has a global namespace so you may not name a bucket with the same name as an existing bucket. Choose a name that is not being used.


Question: How can I serve my content over HTTPS without using a load balancer

Solution:
 You can serve static content through HTTPS using direct URIs such as https://storage.googleapis.com/my-bucket/my-object. For other options to serve your content through a custom domain over SSL, you can:

1. Use a third-party Content Delivery Network with Cloud Storage.
2. Serve your static website content from Firebase Hosting instead of Cloud Storage.


Question:
I get an Access denied error message for a web page served by my
website

Solution:
Check that the object is shared publicly.
If you previously uploaded and shared an object, but then upload a new version of it, then you must reshare the object publicly. This is because the public permission is replaced with the new upload.


Question: I get an error when I attempt to make my data public

Solution: Make sure that you have the setIamPolicy permission for your object or bucket. This permission is granted, for example, in the Storage Admin role. If you have the setIamPolicy permission and you still get an error, your bucket might be subject to public access prevention, which does not allow access to allUsers or allAuthenticatedUsers. Public access prevention might be set on the bucket directly, or it might be enforced through an organization policy that is set at a higher level.


Question:
 I am prompted to download my page's content, instead of being able to
view it in my browser.

Solution:
If you specify a MainPageSuffix as an object that does not have a web
 content type, then instead of serving the page, site visitors are prompted to download the content. To resolve this issue, update the content-type metadata entry to a suitable value, such as text/html.


Question: I'm seeing increased latency when uploading or downloading

Solution:
Use the gsutil perfdiag command to run performance diagnostics from the affected environment. Consider the following common causes of upload and download latency:

CPU or memory constraints: The affected environment's operating system should have tooling to measure local resource consumption such as CPU usage and memory usage.

Disk IO constraints: As part of the gsutil perfdiag command, use the rthru_file and wthru_file tests to gauge the performance impact caused by local disk IO.

Geographical distance: Performance can be impacted by the physical separation of your Cloud Storage bucket and affected environment, particularly in cross-continental cases. Testing with a bucket located in the same region as your affected environment can identify the extent to which geographic separation is contributing to your latency.

If applicable, the affected environment's DNS resolver should use the EDNS(0) protocol so that requests from the environment are routed through an appropriate Google Front End.


Question:
I'm seeing increased latency when accessing Cloud Storage with gcloud
storage, gsutil, or one of the client libraries.

Solution:
The CLIs and the client libraries automatically retry requests when it's
 useful to do so, and this behavior can effectively increase latency as seen from the end user. Use the Cloud Monitoring metric storage.googleapis.com/api/request_count to see if Cloud Storage is consistenty serving a retryable response code, such as 429 or 5xx.


Question:
Do I need to enable billing if I was granted access to someone else's
bucket?

Solution: No, in this case another individual has already set up a Google Cloud project and either granted you access to the entire project or to one of their buckets and the objects it contains. Once you authenticate, typically with your Google account, you can read or write data according to the access that you were granted.


Question:
While performing a resumable upload, I received error and the
message Failed to parse Content-Range header.

Solution: he value you used in your Content-Range header is invalid. For example, Content-Range: */* is invalid and instead should be specified as Content-Range: bytes */*. If you receive this error, your current resumable upload is no longer active, and you must start a new resumable upload.


Question:
Requests to a public bucket directly, or via Cloud CDN, are failing with a
HTTP 401: Unauthorized and an Authentication Required response.

Solution:
Check that your client, or any intermediate proxy, is not adding an
Authorization header to requests to Cloud Storage. Any request with an Authorization header, even if empty, is validated as if it were an authentication attempt.


Question:
How to get data that is older than 6 weeks from GCP metrics explorer
API

Solution:
By Default monitoring API stores data only up to 6 weeks only. If you
need data for more than 6 weeks or long term data then as per data retention policy you can extend up to 24 months. There is no additional cost for this extended retention policy.


Question: How can I maximize the availability of my data?

Solution:
Consider storing your data in a multi-region or dual-region bucket location if high availability is a top requirement. All data is stored geo-redundantly in these locations, which means your data is stored in at least two geographically separated regions. In the unlikely event of a region-wide outage, such as one caused by a natural disaster, buckets in geo-redundant locations remain available, with no need to change storage paths. Also,
 because object listing in a bucket is always strongly consistent, regardless of bucket location, there is a zero recovery time objective (RTO) in most circumstances for dual- and multi-regions. Note that to achieve uninterrupted service, other products, such as Compute Engine instances, must be set up to be geo-redundant as well.


Question: How can I get a summary of space usage for a Cloud Storage bucket?

Solution:
You can use Cloud Monitoring for daily monitoring of your bucket's byte
 count, or you can use the gsutil du command to get the total bytes in your bucket at a given moment. For more information, see Getting a bucket's size.


Question: I created a bucket, but don't remember which project I created it in. How can I find it?

Solution:
For most common Cloud Storage operations, you only need to specify the relevant bucket's name, not the project associated with the bucket. In general, you only need to specify a project identifier when creating a bucket or listing buckets in a project. For more information, see When to specify a project.

To find which project contains a specific bucket:

If you are searching over a moderate number of projects and buckets, use the Google Cloud console, select each project, and view the buckets it contains.
Otherwise, go to the storage.bucket.get page in the API Explorer and enter the bucket's name in the bucket field. When you click Authorize and Execute, the associated project number appears as part of the response. To get the project name, use the project number in the following terminal command:

gcloud projects list | grep PROJECT_NUMBER


Question: How do I prevent race conditions for my Cloud Storage resources?

Solution:
The easiest way to avoid race conditions is to use a naming scheme that
 avoids more than one mutation of the same object name. Often such a design is not feasible, in which case you can use preconditions in your request. Preconditions allow the request to proceed only if the actual state of the resource matches the criteria specified in the preconditions.


Question: How do I Reset Google Cloud?

Solution:
f you need to reset your Google Cloud for any reason, you can reset Google Cloud by following the steps below.

1. First of all you need to go to Google Cloud Console (https://console.cloud.google.com/) and then you need to sign in with your Google Account.

2. And then from the console dashboard, you need to select the project you want to reset.

3. And then you need to click on the gear icon in the top-right corner to access the project settings.

4. And now you have to scroll down to the "Shut Down" section and then you have to click on the "Shut Down" button.

5. And now you have to confirm that you want to close the project by typing the Project ID in the text field provided.

6. Finally you have to click on the "Shut Down" button again to confirm the action.


Question: Unable to view or edit a shared Google Drive access.

Solution: If that is the case then ask the owner to give you the access and then the issue should be resolved.


Question: Unable to access the latest version of Google Cloud.

Solution:
If that is the case then all you need to do is update your Google Cloud
to latest version so that the same is resolved.


Question: Google Cloud is not being able to perform print operations

Solution:
In such cases simply check for updates in your printer and update
 immediately to fix the same


Question: I should have permission to access a certain bucket or object, but when I attempt to do so, I get a 403 - Forbidden error with a message that is similar to: example@email.com does not have storage.objects.get access to the Google Cloud Storage object.

Solution:
You are missing a IAM permission for the bucket or object that is required to complete the request. If you expect to be able to make the request but cannot, perform the following checks:

1. Is the grantee referenced in the error message the one you expected? If the error message refers to an unexpected email address or to "Anonymous caller", then your request is not using the credentials you intended. This could be because the tool you are using to make the request was set up with the credentials from another alias or entity, or it could be because the request is being made on your behalf by a service account.

2. Is the permission referenced in the error message one thought you needed? If the permission is unexpected, it's likely because the tool you're using requires additional access in order to complete your request. For example, in order to bulk delete objects in a bucket, gcloud must first construct a list of objects in the bucket to delete. This portion of the bulk delete action requires the storage.objects.list permission, which might be surprising, given that the goal is object deletion, which normally requires only the storage.objects.delete permission. If this is the cause of your error message, make sure you're granted IAM roles that have the additional necessary permissions.

3. Are you granted the IAM role on the intended resource or parent resource? For example, if you're granted the Storage Object Viewer role for a project and you're trying to download an object, make sure the object is in a bucket that's in the project; you might inadvertently have the Storage Object Viewer permission for a different project.


Question: Lost connection to MySQL server during query when dumping table

Solution:
The source may have become unavailable, or the dump contained packets too large.
Make sure the external primary is available to connect, or use mysqldump with the max_allowed_packet option.


Question: The initial data migration was successful, but no data is being replicated.

Solution:
One possible root cause could be your source database has defined replication flags which result in some or all database changes not being replicated over.
Make sure the replication flags such as binlog-do-db, binlog-ignore-db, replicate-do-db or replicate-ignore-db are not set in a conflicting way.

Run the command show master status on the primary instance to see the current settings.


Question:
The initial data migration was successful but data replication stops
working after a while.

Solution:
Things to try:
1. Check the replication metrics for your replica instance in the Cloud Monitoring section of the Google Cloud console.
2. The errors from the MySQL IO thread or SQL thread can be found in Cloud Logging in the mysql.err log files.
3. The error can also be found when connecting to the replica instance. Run the command SHOW SLAVE STATUS, and check for the following fields in the output:
   Slave_IO_Running
   Slave_SQL_Running
   Last_IO_Error
   Last_SQL_Error


Question: I am getting an error as mysqld check failed: data disk is full.

Solution:
The data disk of the replica instance is full.
Increase the disk size of the replica instance. You can either manually increase the disk size or enable auto storage increase.


Question:
Error message: The slave is connecting ... master has purged binary logs
containing GTIDs that the slave requires.

Solution:
The primary Cloud SQL instance has automatic backups and binary logs and point-in-time recovery is enabled, so it should have enough logs for the replica to be able to catch up. However, in this case although the binary logs exist, the replica doesn't know which row to start reading from.
Create a new dump file using the correct flag settings, and configure the external replica using that file

1. Connect to your mysql client through a Compute Engine instance.
2. Run mysqldump and use the --master-data=1 and --flush-privileges flags.
Important: Do not include the --set-gtid-purged=OFF flag.

Learn more.

3. Ensure that the dump file just created contains the SET @@GLOBAL.GTID_PURGED='...' line.
4. Upload the dump file to a Cloud Storage bucket and configure the replica using the dump file.


Question: After enabling a flag the instance loops between panicking and crashing.

Solution:
Contact customer support to request flag removal followed by a hard
drain. This forces the instance t restart on a different host with a fresh configuration without the undesired flag or setting.


Question:
Getting the error message Bad syntax for dict arg when trying to set a
flag.

Solution: Complex parameter values, such as comma-separated lists, require special treatment when used with gcloud commands.


Question:
HTTP Error 409: Operation failed because another operation was already
in progress.

Solution:
There is already a pending operation for your instance. Only one
operation is allowed at a time. Try your request after the current operation is complete.


Question: The import operation is taking too long.

Solution:
Too many active connections can interfere with import operations.
Close unused operations. Check the CPU and memory usage of your Cloud SQL instance to make sure there are plenty of resources available. The best way to ensure maximum resources for the import is to restart the instance before beginning the operation.

A restart:

Closes all connections.
Ends any tasks that may be consuming resources.


Question: An import operation failing with an error that a table doesn't exist.

Solution:
Tables can have foreign key dependencies on other tables, and depending on the order of operations, one or more of those tables might not yet exist during the import operation.
Things to try:

Add the following line at the start of the dump file:
SET FOREIGN_KEY_CHECKS=0;

Additionally, add this line at the end of the dump file:
SET FOREIGN_KEY_CHECKS=1;

These settings deactivate data integrity checks while the import operation is in progress, and reactivate them after the data is loaded. This doesn't affect the integrity of the data on the database, because the data was already validated during the creation of the dump file.


Question: getting Operations information is not found in logs as an error

Solution:
You want to find more information about an operation.
For example, a user was deleted but you can't find out who did it. The logs show the operation started but don't provide any more information. You must enable audit logging for detailed and personal identifying information (PII) like this to be logged.


Question: Slow performance after restarting MySQL.

Solution:
Cloud SQL allows caching of data in the InnoDB buffer pool. However,
after a restart, this cache is always empty, and all reads require a round trip to the backend to get data. As a result, queries can be slower than expected until the cache is filled.


Question: I am unable to manually delete binary logs.

Solution:
Binary logs cannot be manually deleted. Binary logs are automatically
deleted with their associated automatic backup, which generally happens after about seven days.


Question: How do I find information about temporary files.

Solution:
A file named ibtmp1 is used for storing temporary data. This file is reset upon database restart. To find information about temporary file usage, connect to the database and execute the following query:
SELECT * FROM INFORMATION_SCHEMA.FILES WHERE TABLESPACE_NAME='innodb_temporary'\G


Question: How do I find out about table sizes.

Solution:
This information is available in the database.
Connect to the database and execute the following query:

SELECT TABLE_SCHEMA, TABLE_NAME, sum(DATA_LENGTH+INDEX_LENGTH)/pow(1024,2) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA NOT IN ('PERFORMANCE_SCHEMA','INFORMATION_SCHEMA','SYS','MYSQL') GROUP BY TABLE_SCHEMA, TABLE_NAME;


Question: My data is being automatically deleted.

Solution:
Most likely a script is running somewhere in your environment.
Look in the logs around the time of the deletion and see if there's a rogue script running from a dashboard or another automated process.


Question:
When I am trying to delete a user getting error message as user cannot be
deleted.

Solution:
The user probably has objects in the database that depend on it. You need to drop those objects or reassign them to another user.
Find out which objects are dependent on the user, then drop or reassign those objects to a different user.


Question: Unable to create read replica - unknown error.

Solution:
There's probably a more specific error in the log files. Inspect the logs in Cloud Logging to find the actual error.
If the error is: set Service Networking service account as servicenetworking.serviceAgent role on consumer project, then disable and re-enable the Service Networking API. This action creates the service account necessary to continue with the process.


Question: While changing parallel replication flags resulting an error.

Solution:
An incorrect value is set for one of or more of these flags.
On the primary instance that's displaying the error message, set the parallel replication flags:

1. Modify the binlog_transaction_dependency_tracking and transaction_write_set_extractionflags:
binlog_transaction_dependency_tracking=COMMIT_ORDER
transaction_write_set_extraction=OFF

2. Add the slave_pending_jobs_size_max flag:
slave_pending_jobs_size_max=33554432

3. Modify the transaction_write_set_extraction flag:
transaction_write_set_extraction=XXHASH64

4. Modify the binlog_transaction_dependency_tracking flag:
binlog_transaction_dependency_tracking=WRITESET


Question: getting error when deleting an instance.

Solution:
If deletion protection is enabled for an instance, confirm your plans to
delete the instance. Then disable deletion protection before deleting the instance.


Question: I am not able to see the current operation's status.

Solution:
The Google Cloud console reports only success or failure when the operation is done. It isn't designed to show warnings or other updates
Run the gcloud sql operations list command to list all operations for the given Cloud SQL instance.


Question:
Deployment failure: Insufficient permissions to (re)configure a trigger
(permission denied for bucket <BUCKET_ID>). Please, give owner permissions to the editor role of the bucket and try again.

Solution:
Reset this service account to the default role.
or
Grant the runtime service account the cloudfunctions.serviceAgent role.
or
Grant the runtime service account the storage.buckets.{get, update} and the resourcemanager.projects.get permissions.


Question: Function deployment fails while executing function's global scope

Solution:
For a more detailed error message, look into your function's build logs,
as well as your function's runtime logs. If it is unclear why your function failed to execute its global scope, consider temporarily moving the code into the request invocation, using lazy initialization of the global variables. This allows you to add extra log statements around your client libraries, which could be timing out on their instantiation (especially if they are calling other services), or crashing/throwing exceptions altogether. Additionally, you can try increasing the function timeout.


Question: When a function is attempted to be deployed, its global scope is used.

Solution:
1. Disable Lifecycle Management on the buckets required by Container Registry.
2. Delete all the images of affected functions. You can access build logs to find the image paths. Reference script to bulk delete the images. Note that this does not affect the functions that are currently deployed.
3. Redeploy the functions.


Question: Serving permission error due to "allow internal traffic only" configuration

Solution:
You can:
1. Ensure that the request is coming from your Google Cloud project or VPC Service Controls service perimeter.
or
2. Change the ingress settings to allow all traffic for the function.


Question: Getting error as your client does not have permission to the requested URL

Solution:
Make sure that your requests include an Authorization:
Bearer ID_TOKEN header, and that the token is an ID token, not an access or refresh token. If you are generating this token manually with a service account's private key, you must exchange the self-signed JWT token for a Google-signed Identity token, following this guide.


Question: Attempt to invoke function using curl redirects to Google login page

Solution:
Make sure you specify the name of your function correctly. You can
always check using gcloud functions call which returns the correct 404 error for a missing function.


Question:
error message
In Cloud Logging logs: "Infrastructure cannot communicate with function.
There was likely a crash or deadlock in the user-provided code."

Solution:
Different runtimes can crash under different scenarios. To find the root cause, output detailed debug level logs, check your application logic, and test for edge cases.

The Cloud Functions Python37 runtime currently has a known limitation
on the rate that it can handle logging. If log statements from a Python37 runtime instance are written at a sufficiently high rate, it can produce this error. Python runtime versions >= 3.8 do not have this limitation. We encourage users to migrate to a higher version of the Python runtime to avoid this issue.


Question:
Function stopping in mid-execution, or continues running after my code
finishes

Solution:
If your function terminates early, you should make sure all your function's asynchronous tasks have been completed before doing any of the following:

1. returning a value
2. resolving or rejecting a returned Promise object (Node.js functions only)
3. throwing uncaught exceptions and/or errors
sending an HTTP response
calling a callback function
If your function fails to terminate once all asynchronous tasks have completed, you should verify that your function is correctly signaling Cloud Functions once it has completed. In particular, make sure that you perform one of the operations listed above as soon as your function has finished its asynchronous tasks.


Question:
getting error as User with Project Viewer or Cloud Function role cannot
deploy a function

Solution:
Assign the user an additional role, the Service Account User IAM role
(roles/iam.serviceAccountUser), scoped to the Cloud Functions runtime service account.


Question:
Deployment service account missing the Service Agent role when
deploying functions

Solution: Reset this service account to the default role.


Question:
Deployment service account missing Pub/Sub permissions when
deploying an event-driven function

Solution:
You can:

Reset this service account to the default role.
or
Grant the pubsub.subscriptions.* and pubsub.topics.* permissions to your service account manually.


Question: Getting default runtime service account does not exist as error message

Solution:
1. Specify a user managed runtime service account when deploying your 1st gen functions.
or
2. Recreate the default service account @appspot.gserviceaccount.com for your project.


Question: User with Project Editor role cannot make a function public

Solution:
1. Assign the deployer either the Project Owner or the Cloud Functions Admin role, both of which contain the cloudfunctions.functions.setIamPolicy permission.
or
2.Grant the permission manually by creating a custom role.


Question: Is there a way to keep track of dates on Firestore using cloud functions

Solution:
One approach would be to create a scheduled function that scans your database for documents to update every minute or every five minutes. This is a good approach for popular applications with a consistent usage rate.

To improve efficiency, you can use a Firestore onCreate trigger to defer a Cloud Task Function to update the document. As each purchase is made, a Cloud Task can be scheduled to execute in 72 hours from the purchase date where it sets promo to true. This has the benefit of not running jobs that don't have any documents to update.


Question:
Is it possible to route Google Cloud Functions egress traffic through
multiple rotating IPs?

Solution:
1. Create a Serverless VPC Connector
2. Create a Cloud NAT Gateway and have it include the subnet that you assigned to the Serverless VPC Connector
3. Configure your Cloud Function to use the Serverless VPC Connector for all its egress
Now that specific Cloud Function using that specific VPC Connector will route its outbound traffic through that specific Cloud NAT Gateway.

You can repeat this process as many times as necessary. To make this work with your Cloud Function you will have to deploy them as multiple Cloud Functions rather than a single Cloud Function.


Question: How do I set entry point in cloud function?

Solution:
In the Entry point field, enter the entry point to your function in your
source code. This is the code that will be executed when your function runs. The value of this flag must be a function name or fully-qualified class name that exists in your source code


Question: Serverless VPC Access connector is not ready or does not exist

Solution:
List your subnets to check whether your connector uses a /28 subnet mask.

If it does not, recreate or create a new connector to use a /28 subnet. Note the following considerations:

1. If you recreate the connector, you do not need to redeploy other functions. You might experience a network interruption as the connector is recreated.

2. If you create a new alternate connector, redeploy your functions to use the new connector and then delete the original connector. This method avoids network interruption.


Question: Cloud Functions logs are not appearing in Log Explorer

Solution:
Use the client library interface to flush buffered log entries before
exiting the function or use the library to write log entries synchronously. You can also synchronously write logs directly to stdout or stderr.


Question: Cloud Functions logs are not appearing via Log Router Sink

Solution:
Make sure no exclusion filter is set for
resource.type="cloud_functions"


Question:
Python GCP Cloud function connecting to Cloud SQL Error:
"ModuleNotFoundError: No module named 'google.cloud.sql'"

Solution:
The error “ModuleNotFoundError: No module named 'google.cloud.sql” occurs as the google.cloud.sql module is not installed in the requirement.txt file. You can install it by using the command pip install “google.cloud.sql”

Also I would like to suggest you to check whether you have assigned the “Cloud SQL Client” role to the service account.

Also I would like to suggest you to check whether you have enabled the "Cloud SQL Admin API" within your Google cloud project.

As you already stated VPC connector and Cloud SQL instance are in the same VPC network, also make sure that they are in the same region.

Also check whether the installed packages in the requirements.txt are compatible with your python version you are using.


Question:
Unable to give Cloud Functions Admin role to my account on Firebase's
project setting

Solution:
The origin of this issue is unknow. You can go to Manage roles, find
Cloud Functions Admin and create a custom role out of it. Then you can add this role instead.


Question:
When adding two timed function to the same function app, only one of
them is triggered

Solution:
Could probably be caused by a lot of issues like wrong configuration etc.
 In my case, I had the configuration just right, but found a "feature" in Azure Functions. If adding two timed functions with the same class name and the same schedule, Azure executes one of the two functions twice. Changing the class name in one of the functions fixes the issue.


Question:
Azure Function not triggering when deployed, but works correctly in local
debugging

Solution:
there are a few things you can check and try to resolve the problem:
Check the connection string: Verify that the connection string for the Event Hub trigger in the local.settings.json file and the connection string in the Azure Function App settings are identical (except for the "Endpoint" part). Make sure that the connection string in the Azure Function App settings is using the correct Event Hub namespace and Event Hub name. Check the function.json file: Ensure that your function.json file has the correct configuration for the Event Hub trigger binding. Verify the type, name, direction, eventHubName, and connection properties.


Question:
How do I access a virtual machine through point-to-site VPN from a
Function?

Solution:
You can secure communications between a web app and a virtual
machine using Azure Point-To-Site VPN the solution, is to select App Service Plan in Hosting Plan. Running the Function on the App Service Plan (rather than on the Consumption Plan), opens up for Networking settings in the Function app settings view.


Question: How do I set a static IP in Functions?

Solution:
Deploying a function in an App Service Environment is the primary way to have static inbound and outbound IP addresses for your functions.

You can also use a virtual network NAT gateway to route outbound traffic through a public IP address that you control


Question: How do I restrict internet access to my function?

Solution:
You can restrict internet access in a couple of ways:

1. Private endpoints: Restrict inbound traffic to your function app by private link over your virtual network, effectively blocking inbound traffic from the public internet.
IP restrictions: Restrict inbound traffic to your function app by IP range.
Under IP restrictions, you are also able to configure Service Endpoints, which restrict your Function to only accept inbound traffic from a particular virtual network.
2. Removal of all HTTP triggers. For some applications, it's enough to simply avoid HTTP triggers and use any other event source to trigger your function.
3. Keep in mind that the Azure portal editor requires direct access to your running function. Any code changes through the Azure portal will require the device you're using to browse the portal to have its IP added to the approved list. But you can still use anything under the platform features tab with network restrictions in place.


Question: How do I restrict my function app to a virtual network?

Solution:
You are able to restrict inbound traffic for a function app to a virtual network using Service Endpoints. This configuration still allows the function app to make outbound calls to the internet.

To completely restrict a function such that all traffic flows through a virtual network, you can use a private endpoints with outbound virtual network integration or an App Service Environment.


Question: How can I access resources in a virtual network from a function app?

Solution:
You can access resources in a virtual network from a running function by
 using virtual network integration.


Question: How can I trigger a function from a resource in a virtual network?

Solution:
You are able to allow HTTP triggers to be called from a virtual network using Service Endpoints or Private Endpoint connections.

You can also trigger a function from all other resources in a virtual network by deploying your function app to a Premium plan, App Service plan, or App Service Environment.


Question: How can I deploy my function app in a virtual network?

Solution:
Deploying to an App Service Environment is the only way to create a
function app that's wholly inside a virtual network.


Question: In the Azure portal, it says 'Azure Functions runtime is unreachable'

Solution:
Besides the normal network restrictions that could prevent your
function app from accessing the storage account. Here it mentions an issue where the App_Offline.htm was in the file system, thereby instructing the platform your app is unreachable. It's certainly plausible, so check the kudu system (or az rest) to see if that file exists, remove it, and retry the operation.


Question: Orchestration is stuck in the Pending state

Solution:
Use the following steps to troubleshoot orchestration instances that remain stuck indefinitely in the "Pending" state.

1. Check the Durable Task Framework traces for warnings or errors for the impacted orchestration instance ID. A sample query can be found in the Trace Errors/Warnings section.

2. Check the Azure Storage control queues assigned to the stuck orchestrator to see if its "start message" is still there For more information on control queues, see the Azure Storage provider control queue documentation.

3. Change your app's platform configuration version to “64 Bit”. Sometimes orchestrations don't start because the app is running out of memory. Switching to 64-bit process allows the app to allocate more total memory. This only applies to App Service Basic, Standard, Premium, and Elastic Premium plans. Free or Consumption plans do not support 64-bit processes.


Question:
"ERROR: Exception calling "Fill" with "1" argument(s): "Timeout expired.
The timeout period elapsed prior to completion of the operation or the server is not responding." "

Solution:
Here are the few suggestions:

1. Have you tried with a simple query from Azure Function and worked (different query that executes within few seconds)? If so, then try setting CommandTimeout as 0.
2. Make sure there is a network connectivity between Azure Functions and SQL Server and Function App can access SQL server. Here is doc Typical causes and resolutions for the error with common causes/resolutions. Any VNET integration, Firewall in between services? Review https://learn.microsoft.com/en-us/azure/azure-functions/functions-networking-options?tabs=azure-cli networking set up of Azure Functions and Use tcpping tool to test the connectivity (Tools).


Question:
while creating the function app from the portal the storage section is
missing

Solution:
Retry the same operation by logging-in to portal from different browser
 or signing out and signing-in in same browser or by clearing the browser cache.


Question:
How do I add or access an app.config file in Azure functions to add a
database connection string?

Solution:
The best way to do this is to add a Connection String from the Azure portal:

1. From your Function App UI, click Function App Settings
2. Settings / Application Settings
3. Add connection strings
They will then be available using the same logic as if they were in a web.config, e.g.

var conn = System.Configuration.ConfigurationManager
                 .ConnectionStrings["MyConn"].ConnectionString;


Question: How to rename an Azure Function?

Solution:
The UI does not directly support renaming a Function, but you can work around this using the following manual steps:

1. Stop your Function App. To do this, go under Function app settings / Go To App Service Settings, and click on the Stop button.
2. Go to Kudu Console: Function app settings / Go to Kudu (article about that)
3. In Kudu Console, go to D:\home\site\wwwroot and rename the Function folder to the new name
4. Now go to D:\home\data\Functions\secrets and rename [oldname].json to [newname].json
5. Then go to D:\home\data\Functions\sampledata and rename [oldname].dat to [newname].dat
6. Start your function app, in the same place where you stopped it above In the Functions UI, click the refresh button in the top left corner, and your renamed function should appear


Question: Azure function apps logs not showing

Solution:
The log window is a bit fragile and doesn't always show the logs. However, logs are also written to the log files.

You can access these logs from the Kudu console: https://[your-function-app].scm.azurewebsites.net/

From the menu, select Debug console > CMD

On the list of files, go into LogFiles > Application > Functions > Function > [Name of your function]

There you will see a list of log files.


Question:
How can I use PostgreSQL with Azure Functions without maxing out
connections?

Solution:
This is the classic problem of using shared resources. You have 50 of
these resources in this case. The most effective way to support more consumers would be to reduce the time each consumer uses the resource. Reducing the Connection Idle Lifetime substantially is probably the most effective way. Increasing Timeout does help reduce errors (and is a good choice), but it doesn't increase the throughput. It just smooths out the load. Reducing Maximum Pool size is also good.


Question:
I have a queue based function app, however even after publishing
messages to queue - function does not get triggered?

Solution:
Azure function  expects queue messages to be base64 encoded to trigger it.

So if message pushed to queue is not base64 encoded then the function trigger ignores it.


Question: Azure Functions Cannot Authenticate to Storage Account

Solution:
 Must add the Storage Account user.impersonation permission to the
Service Principal!


Question:
How can I assign Graph Sites.ReadWrite.All permissions in Tenant B to my
Tenant A app?

Solution:
There are two ways to achieve this:
Using App Registration or Federated Managed Identity

App Registration

In order to assign Graph Sites.ReadWrite.All permissions in Tenant B to your Tenant A app, you will need to create an app registration for your Azure Function in Tenant

Here are the steps you can follow:

1)Register your Azure Function in Tenant B: a. Sign in to the Azure portal (https://portal.azure.com/) using an account with admin privileges in Tenant B. b. Navigate to "Azure Active Directory" > "App registrations" > "New registration". c. Provide a name for your app registration (e.g., "AzFunction-TenantB"), and then click "Register".
2)Grant Graph Sites.ReadWrite.All permissions to the app registration in Tenant B: a. In the app registration page for "AzFunction-TenantB", go to "API permissions" > "Add a permission". b. Select "Microsoft Graph" and choose the "Application permissions" tab. c. Expand the "Sites" group and check the "Sites.ReadWrite.All" permission. d. Click "Add permissions" to save your changes.
3)Grant admin consent for the permissions: a. Still in the "API permissions" tab, click on the "Grant admin consent for [Tenant B]" button. You'll need to be an admin in Tenant B to perform this action.
4)(Share the client ID and tenant ID with Tenant A: a. In the "Overview" tab of the "AzFunction-TenantB" app registration, make a note of the "Application (client) ID" and "Directory (tenant) ID" values.
5)Configure your Azure Function in Tenant A to use the new app registration in Tenant B: a. Sign in to the Azure portal (https://portal.azure.com/) using an account with privileges to manage your Azure Function in Tenant A. b. Go to the Azure Function App, navigate to the "Configuration" tab, and update the following values:
TENANT_B_CLIENT_ID: Set this to the "Application (client) ID" from step 4.
TENANT_B_TENANT_ID: Set this to the "Directory (tenant) ID" from step 4.
6)Update your Azure Function code to use the new app registration when calling Microsoft Graph: a. Use the new TENANT_B_CLIENT_ID and TENANT_B_TENANT_ID values when acquiring a token for Microsoft Graph. This will ensure that your Azure Function uses the app registration from Tenant B when calling the API.

Federated Managed Identity

https://svrooij.io/2022/12/16/poc-multi-tenant-managed-identity/#post
https://blog.identitydigest.com/azuread-federate-mi/

Note: You may also need to configure the necessary network and firewall settings to allow access to Tenant B from Tenant A.

You may also want to consider granting the necessary permissions to users in Tenant A to access the data in Tenant B. This can be done using Azure AD B2B collaboration.


Question: Queries using Azure AD authentication fails after 1 hour

Solution:
Following steps can be followed to work around the problem.

1. It's recommended switching to Service Principal, Managed Identity or Shared Access Signature instead of using user identity for long running queries.
2. Restarting client (SSMS/ADS) acquires new token to establish the connection.


Question:
Query failures from serverless SQL pool to Azure Cosmos DB analytical
store

Solution:
following actions can be taken as quick mitigation:

1. Retry the failed query. It will automatically refresh the expired token.
2. Disable the private endpoint. Before applying this change, confirm with your security team that it meets your company security policies.


Question:
Azure Cosmos DB analytical store view propagates wrong attributes in the
column

Solution:
following actions can be taken as quick mitigation:

1. Recreate the view by renaming the columns.
2. Avoid using views if possible.


Question: Failed to delete Synapse workspace & Unable to delete virtual network

Solution: The problem can be mitigated by retrying the delete operation.


Question: synapse notebook connection has closed unexpectedly

Solution:
try to switch your network environment, such as inside/outside corpnet, or access Synapse Notebook on another workstation.

If you can run notebook on the same workstation but in a different network environment, please work with your network administrator to find out whether the WebSocket connection has been blocked.

If you can run notebook on a different workstation but in the same network environment, please ensure you didn’t install any browser plugin that may block the WebSocket request.


Question: Websocket connection was closed unexpectedly.

Solution:
To resolve this issue, rerun your query.
1. Try Azure Data Studio or SQL Server Management Studio for the same queries instead of Synapse Studio for further investigation.
2. If this message occurs often in your environment, get help from your network administrator. You can also check firewall settings, and check the Troubleshooting guide.
3. If the issue continues, create a support ticket through the Azure portal.


Question: Serverless databases aren't shown in Synapse Studio

Solution:
If you don't see the databases that are created in serverless SQL pool,
check to see if your serverless SQL pool started. If serverless SQL pool is deactivated, the databases won't show. Execute any query, for example, SELECT 1, on serverless SQL pool to activate it and make the databases appear.


Question: Synapse Serverless SQL pool shows as unavailable

Solution:
Incorrect network configuration is often the cause of this behavior. Make
sure the ports are properly configured. If you use a firewall or private endpoints, check these settings too.

Finally, make sure the appropriate roles are granted and have not been revoked.


Question: Can't read, list, or access files in Azure Data Lake Storage

Solution:
If you use an Azure AD login without explicit credentials, make sure that your Azure AD identity can access the files in storage. To access the files, your Azure AD identity must have the Blob Data Reader permission, or permissions to List and Read access control lists (ACL) in ADLS. For more information, see Query fails because file cannot be opened.

If you access storage by using credentials, make sure that your managed identity or SPN has the Data Reader or Contributor role or specific ACL permissions. If you used a shared access signature token, make sure that it has rl permission and that it hasn't expired.

If you use a SQL login and the OPENROWSET function without a data source, make sure that you have a server-level credential that matches the storage URI and has permission to access the storage.


Question: query fails with the error File cannot be opened because it does not exist or it is used by another process

Solution:
If your query fails with the error File cannot be opened because it does not exist or it is used by another process and you're sure that both files exist and aren't used by another process, serverless SQL pool can't access the file. This problem usually happens because your Azure AD identity doesn't have rights to access the file or because a firewall is blocking access to the file.

By default, serverless SQL pool tries to access the file by using your Azure AD identity. To resolve this issue, you must have proper rights to access the file. The easiest way is to grant yourself a Storage Blob Data Contributor role on the storage account you're trying to query.


Question: Query fails because it can't be executed due to current resource constraints

Solution:
This message means serverless SQL pool can't execute at this moment. Here are some troubleshooting options:

Make sure data types of reasonable sizes are used.
If your query targets Parquet files, consider defining explicit types for string columns because they'll be VARCHAR(8000) by default. Check inferred data types.
If your query targets CSV files, consider creating statistics.
To optimize your query, see Performance best practices for serverless SQL pool.


Question:
Query fails with the error message Bulk load data conversion error (type
mismatches or invalid character for the specified code page) for row n, column m [columnname] in the data file [filepath].

Solution:
To resolve this problem, inspect the file and the data types you chose. Also
 check if your row delimiter and field terminator settings are correct. The following example shows how inspecting can be done by using VARCHAR as the column type.


Question:
Query fails with the error message Column [column-name] of type
[type-name] is not compatible with external data type […], it's likely that a PARQUET data type was mapped to an incorrect SQL data type.

Solution:
To resolve this issue, inspect the file and the data types you chose. This
mapping table helps to choose a correct SQL data type. As a best practice, specify mapping only for columns that would otherwise resolve into the VARCHAR data type. Avoiding VARCHAR when possible leads to better performance in queries.


Question:
The query references an object that is not supported in distributed
processing mode

Solution:
Some objects, like system views, and functions can't be used while you
query data stored in Azure Data Lake or Azure Cosmos DB analytical storage. Avoid using the queries that join external data with system views, load external data in a temp table, or use some security or metadata functions to filter external data.


Question:
Query returning NULL values instead of partitioning columns or can't find
the partition columns

Solution:
troubleshooting steps:

If you use tables to query a partitioned dataset, be aware that tables don't support partitioning. Replace the table with the partitioned views.
If you use the partitioned views with the OPENROWSET that queries partitioned files by using the FILEPATH() function, make sure you correctly specified the wildcard pattern in the location and used the proper index for referencing the wildcard.
If you're querying the files directly in the partitioned folder, be aware that the partitioning columns aren't the parts of the file columns. The partitioning values are placed in the folder paths and not the files. For this reason, the files don't contain the partitioning values.


Question: Missing column when using automatic schema inference

Solution:
You can easily query files without knowing or specifying schema, by
omitting WITH clause. In that case column names and data types will be inferred from the files. Have in mind that if you are reading number of files at once, the schema will be inferred from the first file service gets from the storage. This can mean that some of the columns expected are omitted, all because the file used by the service to define the schema did not contain these columns. To explicitly specify the schema, please use OPENROWSET WITH clause. If you specify schema (by using external table or OPENROWSET WITH clause) default lax path mode will be used. That means that the columns that don’t exist in some files will be returned as NULLs (for rows from those files). To understand how path mode is used, please check the following documentation and sample.


Question:
Failed to execute query. Error: CREATE EXTERNAL
TABLE/DATA SOURCE/DATABASE SCOPED CREDENTIAL/FILE FORMAT is not supported in master database.

Solution:
1. Create a user database:
CREATE DATABASE <DATABASE_NAME>

2. Execute a CREATE statement in the context of <DATABASE_NAME>, which failed earlier for the master database.

Here's an example of the creation of an external file format:
USE <DATABASE_NAME>
CREATE EXTERNAL FILE FORMAT [SynapseParquetFormat]
WITH ( FORMAT_TYPE = PARQUET)


Question:
Getting an error while trying to create a new Azure AD login or user
in a database

Solution:
check the login you used to connect to your database. The login that's trying to create a new Azure AD user must have permission to access the Azure AD domain and check if the user exists. Be aware that:

SQL logins don't have this permission, so you'll always get this error if you use SQL authentication.
If you use an Azure AD login to create new logins, check to see if you have permission to access the Azure AD domain.


Question:
Resolving Azure Cosmos DB path has failed with error 'This request is not
authorized to perform this operation'.

Solution:
check to see if you used private endpoints in Azure Cosmos DB. To allow
 serverless SQL pool to access an analytical store with private endpoints, you must configure private endpoints for the Azure Cosmos DB analytical store.


Question: Delta table created in Spark is not shown in serverless pool

Solution:
If you created a Delta table in Spark, and it is not shown in the serverless SQL pool, check the following:

1. Wait some time (usually 30 seconds) because the Spark tables are synchronized with delay.
2. If the table didn't appear in the serverless SQL pool after some time, check the schema of the Spark Delta table. Spark tables with complex types or the types that are not supported in serverless are not available. Try to create a Spark Parquet table with the same schema in a lake database and check would that table appears in the serverless SQL pool.
3. Check the workspace Managed Identity access Delta Lake folder that is referenced by the table. Serverless SQL pool uses workspace Managed Identity to get the table column information from the storage to create the table.


Question:
Failed to fetch metadata from the registry, with
reason: generic::permission_denied

Solution:
To resolve this issue, grant the Storage Admin role to the service account:

To see which account you used, run the gcloud auth list command.
To learn why assigning only the App Engine Deployer (roles/appengine.deployer) role might not be sufficient in some cases, see App Engine roles.


Question:
Error: The App Engine appspot and App Engine flexible environment
service accounts must have permissions on the image IMAGE_NAME

Solution:
This error occurs for one of the following reasons:

1. The default App Engine service account does not have the Storage Object Viewer (roles/storage.objectViewer) role.

    To resolve this issue, grant the Storage Object Viewer role to the service account.
2. Your project has a VPC Service Perimeter which limits access to the Cloud Storage API using access levels.

   To resolve this issue, add the service account you use to deploy your app to the corresponding VPC Service Perimeter accessPolicies.


Question: Failed to create cloud build: Permission denied

Solution:
This error occurs if you use the gcloud app deploycommand from an account that does not have the Cloud Build Editor (roles/cloudbuild.builds.editor) role.

To resolve this issue, grant the Cloud Build Editor role to the service account that you are using to deploy your app.

To see which account you used, run the gcloud auth list command.


Question: Timed out waiting for the app infrastructure to become healthy

Solution:
To resolve this issue, rule out the following potential causes:

1. Verify that you have granted the Editor (roles/editor) role to your default App Engine service account.
2. Verify that you have granted the following roles to the service account that you use to run your application (usually the default service account, app-id@appspot.gserviceaccount.com):

    Storage Object Viewer (roles/storage.objectViewer)
    Logs Writer (roles/logging.logWriter)
3. Grant the roles if the service account does not have them.

4. If you are deploying in Shared VPC setup and passing instance_tag in app.yaml, refer to this section to fix the issue.


Question: Invalid value error when deploying in a Shared VPC setup

Solution:
To resolve the issue, remove the instance_tag field from app.yaml and
redeploy.


Question:
Container failed to start. Failed to start and then listen on the port
defined by the PORT environment variable.

Solution:
To resolve this issue, rule out the following potential causes:

Verify that you can run your container image locally. If your container image cannot run locally, you need to diagnose and fix the issue locally first.

Check if your container is listening for requests on the expected port as documented in the container runtime contract. Your container must listen for incoming requests on the port that is defined by Cloud Run and provided in the PORT environment variable. See Configuring containers for instructions on how to specify the port.

Check if your container is listening on all network interfaces, commonly denoted as 0.0.0.0.

Verify that your container image is compiled for 64-bit Linux as required by the container runtime contract.

Note: If you build your container image on a ARM based machine, then it might not work as expected when used with Cloud Run. To solve this issue, build your image using Cloud Build.
Use Cloud Logging to look for application errors in stdout or stderr logs. You can also look for crashes captured in Error Reporting.

You might need to update your code or your revision settings to fix errors or crashes. You can also troubleshoot your service locally.


Question:
The server has encountered an internal error. Please try again later.
Resource readiness deadline exceeded.

Solution:
This issue might occur when the Cloud Run service agent does not exist, or when it does not have the Cloud Run Service Agent (roles/run.serviceAgent) role.

To verify that the Cloud Run service agent exists in your Google Cloud project and has the necessary role, perform the following steps:

Open the Google Cloud console:

Go to the Permissions page

In the upper-right corner of the Permissions page, select the Include Google-provided role grants checkbox.

In the Principals list, locate the ID of the Cloud Run service agent, which uses the ID
service-PROJECT_NUMBER@serverless-robot-prod.iam.gserviceaccount.com.

Verify that the service agent has the Cloud Run Service Agent role. If the service agent does not have the role, grant it.


Question: Can I run Cloud Run applications on a private IP?

Solution:
"Currently no. Cloud Run applications always have a *.run.app public hostname and they cannot be placed inside a VPC (Virtual Private Cloud) network.

If any other private service (e.g. GCE VMs, GKE) needs to call your Cloud Run application, they need to use this public hostname.

With ingress settings on Cloud Run, you can allow your app to be accesible only from the VPC (e.g. VMs or clusters) or VPC+Cloud Load Balancer –but it still does not give you a private IP. You can still combine this with IAM to restrict the outside world but still authenticate and authorize other apps running the VPC network."


Question: The service has encountered an error during container import. Please try again later. Resource readiness deadline exceeded.

Solution:
To resolve this issue, rule out the following potential causes:

1. Ensure container's file system does not contain non-utf8 characters.

2. Some Windows based Docker images make use of foreign layers. Although Container Registry doesn't throw an error when foreign layers are present, Cloud Run's control plane does not support them. To resolve, you may try setting the --allow-nondistributable-artifacts flag in the Docker daemon.
