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.

Add rate limiting protection with Wait nodes and retry logic.

Output:
The node 'Sticky Note2' 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 Note2'.

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 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 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.

The workflow has a broken data flow. The node '7304d9b1-5956-41c3-b78a-2c409d0aa726' is not connected to any subsequent nodes.

**Root Cause**: The connections object is missing the output connections for '7304d9b1-5956-41c3-b78a-2c409d0aa726'.

**Impact**: Data from '7304d9b1-5956-41c3-b78a-2c409d0aa726' 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 '7304d9b1-5956-41c3-b78a-2c409d0aa726' 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": {
  "7304d9b1-5956-41c3-b78a-2c409d0aa726": {
    "main": [[{"node": "NextNode", "type": "main", "index": 0}]]
  }
}
```

Reconnect '7304d9b1-5956-41c3-b78a-2c409d0aa726' to the workflow.

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:
In node 'Error Handler', the parameter 'message' contains an expression that references undefined data.

**Faulty Expression**: `={{ $json["non_existent_field"] }}`
**Original Value**: `Workflow execution error`

**Root Cause**: The expression references a field, node, or variable that doesn't exist in the data flow.

**Debugging Steps**:
1. Check the output of previous nodes to verify available fields
2. Use the Expression Editor to test expressions interactively
3. Add a Set node before this one to inspect available data
4. Use optional chaining for potentially undefined fields: `$json.field?.subfield`

**Best Practice**: Always validate data availability before using expressions.

Fix the expression in 'Error Handler' parameter 'message'.

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:
The workflow has a broken data flow. The node 'f25da511-b255-4a53-ba4e-5765916e90be' is not connected to any subsequent nodes.

**Root Cause**: The connections object is missing the output connections for 'f25da511-b255-4a53-ba4e-5765916e90be'.

**Impact**: Data from 'f25da511-b255-4a53-ba4e-5765916e90be' 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 'f25da511-b255-4a53-ba4e-5765916e90be' 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": {
  "f25da511-b255-4a53-ba4e-5765916e90be": {
    "main": [[{"node": "NextNode", "type": "main", "index": 0}]]
  }
}
```

Reconnect 'f25da511-b255-4a53-ba4e-5765916e90be' to the workflow.

Output:
The node 'Notion' (type: n8n-nodes-base.notion) 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": {
  "notionApi": {
    "id": "03mmrqQX1rffebZp",
    "name": "Notion David"
  }
}
```

**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 'Notion' node.

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:
The workflow has a broken data flow. The node '45076cec-f554-44ae-b314-e43ba080abb5' is not connected to any subsequent nodes.

**Root Cause**: The connections object is missing the output connections for '45076cec-f554-44ae-b314-e43ba080abb5'.

**Impact**: Data from '45076cec-f554-44ae-b314-e43ba080abb5' 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 '45076cec-f554-44ae-b314-e43ba080abb5' 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": {
  "45076cec-f554-44ae-b314-e43ba080abb5": {
    "main": [[{"node": "NextNode", "type": "main", "index": 0}]]
  }
}
```

Reconnect '45076cec-f554-44ae-b314-e43ba080abb5' to the workflow.

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 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.
