Troubleshooting Gmail-Triggered Data Integration from Gemini AI to Google Sheets

Below are a few troubleshooting steps you can take:

Verify Each Step Independently

• Mail Trigger:
  Confirm that your Gmail trigger is firing as expected. Check that the email data you expect is being passed to your workflow. You can add logging to verify that the mail trigger is sending the expected input.

• Gemini AI Agent:
  Ensure that your Gemini AI agent is set up properly. For example, if your input context might be too long, try reducing it or switch temporarily from a model like Gemini 1.5 Pro to Gemini 1.5 Flash. Refer to troubleshooting notes regarding input limits and models in the Gemini documentation.

• Sheets Integration:
  Confirm that your Sheets API credentials and OAuth scopes are correctly configured. Verify that the data passed from the Gemini response is in the format expected by your Sheets calls. It may help to run a simple test script from the Sheets API documentation to ensure your write operations work as intended.

Check Authentication and Authorization

• Verify that all credentials (for Gmail, Gemini, and Sheets) are correct and have the necessary scopes.
• If the OAuth consent screen shows warnings like “This app isn’t verified,” make sure you’re either past the warning during testing or that you’ve configured the app for verification if needed.
• Ensure that tokens haven’t expired or been revoked. If you see errors related to tokens, follow the guidelines on token expiration and refresh.

Error Logging and Feedback

• Look at the error messages returned (both from the Gemini API and Sheets) to identify where the issue is occurring. Sometimes the error details can point you directly to a misconfigured endpoint or invalid payload.
• Use the feedback or logging options provided in AI Studio or your development console to gain more insight into what might be failing.

By checking these pieces individually, you can often pinpoint which integration is causing the fault in your complete workflow. Let me know if you need further details on any specific step.
