Output:
This workflow may experience timeout issues with long-running API requests.

**Symptoms**:
- Execution hangs indefinitely
- Connection timeout errors
- ETIMEDOUT or ESOCKETTIMEDOUT errors

**Root Cause**: No timeout configured for HTTP requests, or external services are slow.

**Solutions**:

1. **Set Appropriate Timeouts**:
```json
"options": {
  "timeout": 30000  // 30 seconds
}
```

2. **Add Error Handling**:
- Use Error Trigger node to catch timeout errors
- Implement fallback logic for failed requests

3. **Use Async Patterns**:
- For long operations, use webhook callbacks
- Implement polling patterns instead of waiting

4. **Configure Node Settings**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 2000,
"continueOnFail": true
```

**Best Practice**: Set reasonable timeouts (10-30 seconds) and always have error handling for external API calls.

Configure appropriate timeouts and error handling for HTTP requests.

Output:
This workflow may encounter rate limiting issues when processing large batches of data.

**Common Rate Limit Errors**:
- HTTP 429 Too Many Requests
- HTTP 503 Service Unavailable
- API-specific rate limit messages

**Root Cause**: The workflow makes too many API requests in a short time period without delays.

**Solutions**:

1. **Add Wait Nodes**: Insert a Wait node between API calls
```json
{
  "parameters": {"amount": 1, "unit": "seconds"},
  "name": "Rate Limit Delay",
  "type": "n8n-nodes-base.wait"
}
```

2. **Enable Retry on Fail**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 5000
```

3. **Use Batch Processing**: Split items into smaller batches with delays

4. **Implement Exponential Backoff**: Increase wait times with each retry

**Best Practice**: Always check API documentation for rate limits and implement appropriate throttling.

Add rate limiting protection with Wait nodes and retry logic.

Output:
This workflow may fail when receiving empty or null input data.

**Common Error Messages**:
- "Cannot read property 'x' of undefined"
- "No items to process"
- "Input data is empty"

**Root Cause**: The workflow doesn't handle cases where:
- Trigger receives no data
- Previous node returns empty array
- API returns null or empty response

**Solutions**:

1. **Add IF Node for Empty Check**:
```json
{
  "parameters": {
    "conditions": {
      "number": [{
        "value1": "={{ $json.length }}",
        "operation": "larger",
        "value2": 0
      }]
    }
  },
  "name": "Check Not Empty",
  "type": "n8n-nodes-base.if"
}
```

2. **Use Default Values**:
```javascript
{{ $json.field ?? "default_value" }}
{{ $json.items || [] }}
```

3. **Add Set Node with Defaults**:
- Create a Set node that provides default values
- Place it early in the workflow

4. **Implement No Match Output**:
- Many nodes have "No Match" outputs
- Use these to handle empty cases gracefully

**Best Practice**: Always validate input data and provide sensible defaults for optional fields.

Add validation for empty or null input data.

**Impact**: Data from '425b3030-d745-4fe0-a489-c6d79f1d6dca' will not flow to any downstream nodes, effectively stopping the workflow at this point.

**Solution**:
1. Open the workflow in the n8n editor
2. Draw a connection from '425b3030-d745-4fe0-a489-c6d79f1d6dca' to the next node in the flow
3. Verify the connection appears in the connections object

**Programmatic Fix**: Add the connection back to the workflow JSON:
```json
"connections": {
  "425b3030-d745-4fe0-a489-c6d79f1d6dca": {
    "main": [[{"node": "NextNode", "type": "main", "index": 0}]]
  }
}
```

Reconnect '425b3030-d745-4fe0-a489-c6d79f1d6dca' to the workflow.

Output:
This workflow may experience timeout issues with long-running API requests.

**Symptoms**:
- Execution hangs indefinitely
- Connection timeout errors
- ETIMEDOUT or ESOCKETTIMEDOUT errors

**Root Cause**: No timeout configured for HTTP requests, or external services are slow.

**Solutions**:

1. **Set Appropriate Timeouts**:
```json
"options": {
  "timeout": 30000  // 30 seconds
}
```

2. **Add Error Handling**:
- Use Error Trigger node to catch timeout errors
- Implement fallback logic for failed requests

3. **Use Async Patterns**:
- For long operations, use webhook callbacks
- Implement polling patterns instead of waiting

4. **Configure Node Settings**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 2000,
"continueOnFail": true
```

**Best Practice**: Set reasonable timeouts (10-30 seconds) and always have error handling for external API calls.

Output:
This workflow may fail when receiving empty or null input data.

**Common Error Messages**:
- "Cannot read property 'x' of undefined"
- "No items to process"
- "Input data is empty"

**Root Cause**: The workflow doesn't handle cases where:
- Trigger receives no data
- Previous node returns empty array
- API returns null or empty response

**Solutions**:

1. **Add IF Node for Empty Check**:
```json
{
  "parameters": {
    "conditions": {
      "number": [{
        "value1": "={{ $json.length }}",
        "operation": "larger",
        "value2": 0
      }]
    }
  },
  "name": "Check Not Empty",
  "type": "n8n-nodes-base.if"
}
```

2. **Use Default Values**:
```javascript
{{ $json.field ?? "default_value" }}
{{ $json.items || [] }}
```

3. **Add Set Node with Defaults**:
- Create a Set node that provides default values
- Place it early in the workflow

4. **Implement No Match Output**:
- Many nodes have "No Match" outputs
- Use these to handle empty cases gracefully

**Best Practice**: Always validate input data and provide sensible defaults for optional fields.

Output:
The node 'Get all your team's tickets' (type: n8n-nodes-base.graphql) requires credentials but the 'credentials' configuration is missing.

**Root Cause**: The credentials object was not defined for this node.

**Solution**: Add the credentials configuration back to the node:
```json
"credentials": {
  "httpHeaderAuth": {
    "id": "QNQL42DMISvQl50S",
    "name": "Linear api "
  }
}
```

**Best Practice**: Always verify credentials are properly configured before deploying workflows. Use n8n's credential management system to store sensitive data securely.

Add credentials configuration to the 'Get all your team's tickets' node.

Output:
The node 'Send Gmail' (type: n8n-nodes-base.gmail) requires credentials but the 'credentials' configuration is missing.

**Root Cause**: The credentials object was not defined for this node.

**Solution**: Add the credentials configuration back to the node:
```json
"credentials": {
  "gmailOAuth2": {
    "id": "nx3IJyQ7TuVxI0y2",
    "name": "Gmail account"
  }
}
```

**Best Practice**: Always verify credentials are properly configured before deploying workflows. Use n8n's credential management system to store sensitive data securely.

Add credentials configuration to the 'Send Gmail' node.

Output:
This workflow may fail when receiving empty or null input data.

**Common Error Messages**:
- "Cannot read property 'x' of undefined"
- "No items to process"
- "Input data is empty"

**Root Cause**: The workflow doesn't handle cases where:
- Trigger receives no data
- Previous node returns empty array
- API returns null or empty response

**Solutions**:

1. **Add IF Node for Empty Check**:
```json
{
  "parameters": {
    "conditions": {
      "number": [{
        "value1": "={{ $json.length }}",
        "operation": "larger",
        "value2": 0
      }]
    }
  },
  "name": "Check Not Empty",
  "type": "n8n-nodes-base.if"
}
```

2. **Use Default Values**:
```javascript
{{ $json.field ?? "default_value" }}
{{ $json.items || [] }}
```

3. **Add Set Node with Defaults**:
- Create a Set node that provides default values
- Place it early in the workflow

4. **Implement No Match Output**:
- Many nodes have "No Match" outputs
- Use these to handle empty cases gracefully

**Best Practice**: Always validate input data and provide sensible defaults for optional fields.

Output:
This workflow may encounter rate limiting issues when processing large batches of data.

**Common Rate Limit Errors**:
- HTTP 429 Too Many Requests
- HTTP 503 Service Unavailable
- API-specific rate limit messages

**Root Cause**: The workflow makes too many API requests in a short time period without delays.

**Solutions**:

1. **Add Wait Nodes**: Insert a Wait node between API calls
```json
{
  "parameters": {"amount": 1, "unit": "seconds"},
  "name": "Rate Limit Delay",
  "type": "n8n-nodes-base.wait"
}
```

2. **Enable Retry on Fail**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 5000
```

3. **Use Batch Processing**: Split items into smaller batches with delays

4. **Implement Exponential Backoff**: Increase wait times with each retry

**Best Practice**: Always check API documentation for rate limits and implement appropriate throttling.

Output:
This workflow may fail when receiving empty or null input data.

**Common Error Messages**:
- "Cannot read property 'x' of undefined"
- "No items to process"
- "Input data is empty"

**Root Cause**: The workflow doesn't handle cases where:
- Trigger receives no data
- Previous node returns empty array
- API returns null or empty response

**Solutions**:

1. **Add IF Node for Empty Check**:
```json
{
  "parameters": {
    "conditions": {
      "number": [{
        "value1": "={{ $json.length }}",
        "operation": "larger",
        "value2": 0
      }]
    }
  },
  "name": "Check Not Empty",
  "type": "n8n-nodes-base.if"
}
```

2. **Use Default Values**:
```javascript
{{ $json.field ?? "default_value" }}
{{ $json.items || [] }}
```

3. **Add Set Node with Defaults**:
- Create a Set node that provides default values
- Place it early in the workflow

4. **Implement No Match Output**:
- Many nodes have "No Match" outputs
- Use these to handle empty cases gracefully

**Best Practice**: Always validate input data and provide sensible defaults for optional fields.

Output:
This workflow may experience timeout issues with long-running API requests.

**Symptoms**:
- Execution hangs indefinitely
- Connection timeout errors
- ETIMEDOUT or ESOCKETTIMEDOUT errors

**Root Cause**: No timeout configured for HTTP requests, or external services are slow.

**Solutions**:

1. **Set Appropriate Timeouts**:
```json
"options": {
  "timeout": 30000  // 30 seconds
}
```

2. **Add Error Handling**:
- Use Error Trigger node to catch timeout errors
- Implement fallback logic for failed requests

3. **Use Async Patterns**:
- For long operations, use webhook callbacks
- Implement polling patterns instead of waiting

4. **Configure Node Settings**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 2000,
"continueOnFail": true
```

**Best Practice**: Set reasonable timeouts (10-30 seconds) and always have error handling for external API calls.

Output:
This workflow may encounter rate limiting issues when processing large batches of data.

**Common Rate Limit Errors**:
- HTTP 429 Too Many Requests
- HTTP 503 Service Unavailable
- API-specific rate limit messages

**Root Cause**: The workflow makes too many API requests in a short time period without delays.

**Solutions**:

1. **Add Wait Nodes**: Insert a Wait node between API calls
```json
{
  "parameters": {"amount": 1, "unit": "seconds"},
  "name": "Rate Limit Delay",
  "type": "n8n-nodes-base.wait"
}
```

2. **Enable Retry on Fail**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 5000
```

3. **Use Batch Processing**: Split items into smaller batches with delays

4. **Implement Exponential Backoff**: Increase wait times with each retry

**Best Practice**: Always check API documentation for rate limits and implement appropriate throttling.

Output:
The node 'Survey Insights Agent' has a data type mismatch in its parameters.

**Issue**: A field expected a number but received a string value.

**Common Causes**:
1. Expression returns string instead of number
2. JSON parsing preserves string types for numeric values
3. Upstream node outputs different data types than expected

**Solutions**:

1. **Type Conversion in Expression**:
```javascript
// Convert string to number
{ parseInt($json.stringValue) }
{ parseFloat($json.decimalString) }
{ Number($json.value) }
```

2. **Use Code Node for Transformation**:
```javascript
return items.map(item => {
  item.json.numericField = Number(item.json.stringField);
  return item;
});
```

3. **Validate Data Types**:
- Use IF node to check types before processing
- Add error handling for invalid types

**Best Practice**: Always validate and transform data types explicitly when passing data between nodes.

Fix data type conversion in 'Survey Insights Agent'.

Output:
The node 'Sticky Note3' has a data type mismatch in its parameters.

**Issue**: A field expected a number but received a string value.

**Common Causes**:
1. Expression returns string instead of number
2. JSON parsing preserves string types for numeric values
3. Upstream node outputs different data types than expected

**Solutions**:

1. **Type Conversion in Expression**:
```javascript
// Convert string to number
{ parseInt($json.stringValue) }
{ parseFloat($json.decimalString) }
{ Number($json.value) }
```

2. **Use Code Node for Transformation**:
```javascript
return items.map(item => {
  item.json.numericField = Number(item.json.stringField);
  return item;
});
```

3. **Validate Data Types**:
- Use IF node to check types before processing
- Add error handling for invalid types

**Best Practice**: Always validate and transform data types explicitly when passing data between nodes.

Fix data type conversion in 'Sticky Note3'.

Output:
This workflow may encounter rate limiting issues when processing large batches of data.

**Common Rate Limit Errors**:
- HTTP 429 Too Many Requests
- HTTP 503 Service Unavailable
- API-specific rate limit messages

**Root Cause**: The workflow makes too many API requests in a short time period without delays.

**Solutions**:

1. **Add Wait Nodes**: Insert a Wait node between API calls
```json
{
  "parameters": {"amount": 1, "unit": "seconds"},
  "name": "Rate Limit Delay",
  "type": "n8n-nodes-base.wait"
}
```

2. **Enable Retry on Fail**:
```json
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 5000
```

3. **Use Batch Processing**: Split items into smaller batches with delays

4. **Implement Exponential Backoff**: Increase wait times with each retry

**Best Practice**: Always check API documentation for rate limits and implement appropriate throttling.

```json
"credentials": {
  "spotifyOAuth2Api": {
    "id": "4AquI6TQMHILfmvx",

Output:
This workflow may fail when receiving empty or null input data.

**Common Error Messages**:
- "Cannot read property 'x' of undefined"
- "No items to process"
- "Input data is empty"

**Root Cause**: The workflow doesn't handle cases where:
- Trigger receives no data
- Previous node returns empty array
- API returns null or empty response

**Solutions**:

1. **Add IF Node for Empty Check**:
```json
{
  "parameters": {
    "conditions": {
      "number": [{
        "value1": "={{ $json.length }}",
        "operation": "larger",

      }]
    }
  },
  "name": "Check Not Empty",
  "type": "n8n-nodes-base.if"
}
```

2. **Use Default Values**:
```javascript
{{ $json.field ?? "default_value" }}
{{ $json.items || [] }}
```

3. **Add Set Node with Defaults**:
- Create a Set node that provides default values
- Place it early in the workflow

4. **Implement No Match Output**:
- Many nodes have "No Match" outputs
- Use these to handle empty cases gracefully

**Best Practice**: Always validate input data and provide sensible defaults for optional fields.

**Impact**: Data from '0a36ba22-90b2-4abf-943b-c1cc8e7317d5' will not flow to any downstream nodes, effectively stopping the workflow at this point.

**Solution**:
1. Open the workflow in the n8n editor
2. Draw a connection from '0a36ba22-90b2-4abf-943b-c1cc8e7317d5' to the next node in the flow
3. Verify the connection appears in the connections object

**Programmatic Fix**: Add the connection back to the workflow JSON:
```json
"connections": {
  "0a36ba22-90b2-4abf-943b-c1cc8e7317d5": {
    "main": [[{"node": "NextNode", "type": "main", "index": 0}]]
  }
}
```

Reconnect '0a36ba22-90b2-4abf-943b-c1cc8e7317d5' to the workflow.

Output:
The node 'upload draft email' (type: n8n-nodes-base.httpRequest) requires credentials but the 'credentials' configuration is missing.

**Root Cause**: The credentials object was not defined for this node.

**Solution**: Add the credentials configuration back to the node:
```json
"credentials": {
  "httpHeaderAuth": {
    "id": "3IRsYkeB2ofrwQjv",
    "name": "Fastmail"
  }
}
```

**Best Practice**: Always verify credentials are properly configured before deploying workflows. Use n8n's credential management system to store sensitive data securely.

Add credentials configuration to the 'upload draft email' node.
