How can I debug missing error logs in my Zoom meeting webhook workflow?

Below is a step-by-step approach to debug your workflow when errors don’t show up in the Executions log:

---

1. Check Your Error Workflow Configuration

If you have an Error Workflow configured (using an Error Trigger node), any errors may be caught and routed there instead of appearing in the Executions log for the main workflow. To debug:

• Temporarily disable your Error Workflow assignment in the Workflow Settings. This allows errors to surface directly in the main workflow’s execution logs.
• Run or trigger the workflow again so you can see the error details in the main execution log.

---

2. View the Executions Log

n8n maintains an Executions log that shows details about each run. To inspect it:

• Click the Executions option in the left-side panel of the Editor UI.
• Locate the run corresponding to your webhook trigger.
• Click the View button or the execution name to see node-level details. This can help pinpoint at which step the error occurs.

---

3. Use a Stop and Error Node (Temporarily)

Adding a Stop and Error node in your workflow (for testing purposes) can help you confirm whether the issue is data-related. This node will throw an error and display a custom message from the node. By doing so:

• You can ensure that errors are indeed captured in the log.
• Compare the error message with your expectations to narrow down whether the error stems from a mismatch in the meeting data format, missing fields, or something else.

Example snippet for a Stop and Error node setup:

JSONCopied
{
	"type": "n8n-nodes-base.stopAndError",
	"name": "Stop and Error",
	"parameters": {
		"errorMessage": "Unexpected data format in meeting event"
	},
	"position": [500, 300]
}

4. Verify the Incoming Data

Since your workflow starts with a webhook receiving various events, it’s crucial to inspect the incoming JSON:

• Use a Set node or a simple Function node right after the webhook node.
• Output the full data payload to ensure you’re handling every case (like meetings with/without recordings).

For example, in a Function node, you might log the incoming data:

JAVASCRIPTCopied
// Log the incoming webhook payload
console.log($json);
return $json;

Run the workflow manually (or trigger it) and check the n8n logs (or the browser console if using a debug mode) for irregularities in the data.

5. Check Global Settings and Environment Logs

If nothing appears in the Executions log:

• Ensure that the workflow is active and not just running in test mode.
• Confirm that n8n’s logging level is set appropriately to capture errors. Sometimes errors might only be visible in the system logs or the terminal where n8n runs.

---

By following these steps, you should be able to identify whether errors originate from data inconsistencies in some meeting events or from other configuration issues. Adjust your workflow accordingly once you pinpoint the problem.

Happy debugging!

Below is a list of suggestions you can try to debug the issue:

1. Verify the Webhook URL

Ensure you’re triggering the correct URL. Remember that n8n generates both a Test URL (available for 120 seconds while listening for test events) and a Production URL (active once the workflow is activated). If you’re testing, confirm you’re using the Test URL so you can capture execution logs.

2. Check the Incoming Payload

Sometimes the error can be caused by unexpected data in the incoming payload from Zoom. To help narrow this down, add a simple node (like a Set node) immediately after the Webhook node to capture and log all incoming data. This will let you inspect the payload and see if there’s any unexpected structure or missing fields.

For example:

JSONCopied
{
  "nodes": [
    {
      "parameters": {
        "values": {
          "string": [
            {
              "name": "incomingData",
              "value": "={{$json}}"
            }
          ]
        }
      },
      "name": "Log Payload",
      "type": "n8n-nodes-base.set",
      "typeVersion": 1,
      "position": [450, 300]
    }
  ]
}

This way, you can verify if the webhook is indeed delivering the correct data and if any fields contain unexpected values.

3. Test the Webhook Manually

Using a tool like curl (or Postman) to simulate a webhook call with sample data similar to what Zoom sends can help you pinpoint where the error occurs. For example:

SHCopied
curl --request POST <YOUR_WEBHOOK_URL> --header 'Content-Type: application/json' --data '{"event": "recording.completed", "payload": { ... } }'

Replace <YOUR_WEBHOOK_URL> with the Test or Production URL, and adjust the JSON payload as needed.

4. Check for Node-Specific Issues

Since your workflow is processing meeting data (likely with further nodes following the initial webhook):

• Review the Zoom node setup (if you’re using it later in the workflow) to ensure it can handle all variations of the data coming from Zoom, especially if some meeting records are missing certain fields.
• Verify that your authentication credentials for Zoom are valid and that your OAuth2 setup is current (as JWT tokens have been deprecated).

5. Enable Detailed Logging

If your workflow triggers but shows nothing in the executions:

• Look into your n8n log settings. Running n8n in debug mode or checking the logs from your server can provide additional insights into errors that might not be visible in the default execution details.
• Make sure error outputs are not being suppressed. If a node fails and you have no error handling, the execution might not appear in the usual results.

6. Validate HTTP Methods on the Webhook Node

By default the Webhook node accepts only one HTTP method (GET or POST). If Zoom might send different methods, consider enabling the “Allow Multiple HTTP Methods” option in the Webhook node’s settings. This can prevent issues if Zoom sends events using different HTTP methods.

By following these steps, you should be able to narrow down whether the issue lies with the incoming data, the workflow configuration (including error handling), or perhaps with how the Webhook node is set up. Once you’ve identified where things go wrong, you can adjust the workflow accordingly.
