n8n: Gmail HITL Webhook Not Triggering and Pinecone API Key Issue

Below are a couple of suggestions based on our current documentation and changelog information:

---

1. Gmail “Human in the Loop” Module Issue

The new Human in the Loop (HITL) functionality in the Gmail node uses a webhook mechanism to capture your response (e.g. “Approve” or “Deny”). If you notice that nothing happens after you click one of these buttons, try the following:

• Verify the Webhook Setup:
  Make sure that the workflow is activated and that you’re using the correct webhook URL. During development you may be using the test URL; remember that once you switch to production the generated production URL is used for incoming events.

• Check Network / Reverse Proxy Settings:
  If your instance is running behind a reverse proxy, verify that your proxy is forwarding incoming webhook calls (and websocket calls, if applicable). Incorrect configuration here can prevent the response from reaching the workflow.

• Review the Node Configuration:
  Double-check that the node’s configuration (including any response mapping steps with an Edit Fields node) follows the guidelines outlined in similar webhook integration sections. Sometimes minor differences in response format can cause the webhook not to trigger as expected.

If the problem persists after these checks, it might help to search the community forums for recent reports or updates regarding the new HITL functionality.

2. Pinecone Credential Issue

For the problem with your Pinecone credential not connecting when entering the API key, please consider:

• Validating the API Key:
  Confirm the API key is correct and active. Double-check for any extra spaces or typographical errors when pasting the key.

• Credential Configuration:
  Some services like Pinecone might require additional parameters (like a region or project identifier). Ensure you have entered all necessary parameters as specified in the Pinecone integration documentation.

• Network or Firewall Issues:
  Verify that your server (in this case, running at Hetzner) is allowed to make outbound connections to Pinecone’s API endpoints. Sometimes firewall or network restrictions can block the connection.

• Recreate the Credential:
  Try deleting the existing credential in n8n and re-adding it from scratch. This can often help if there was a temporary misconfiguration.

If none of these steps resolve your issues, it might be helpful to check for any recent discussions on our community forum or file an issue with detailed logs. This helps the team diagnose whether there might be an update-specific bug that requires further attention.

Hope this helps!
