I have a vapi agent setup to check the existing calendar event and they are tied using webhook, I see vapi is invoking the tool to check the results and when results are returned it says no results found. I have confirmed the same using webhook logs. Attaching documents containing all the information 1. Webhook results 2. Call log details 3. Build details Please help out https://cdn.discordapp.com/attachments/1371379619038498847/1371379619198140476/Tool_call_result.docx?ex=6822ec4c&is=68219acc&hm=8569b7f4044ba182b545e2244ac08beeacd54c29b09c5103b6a4f2c1e49e42d8&

Make sure to set up Google Calendar correctly. Check that the webhook provides structured JSON responses with the right parameters. Verify that the time zones are consistent. Add error handling and test with sample data to ensure everything integrates well.

Is the response in json is mandatory?

Yes it's is!

Ohok...let me check

Vapi likely doesn’t recognize your n8n JSON response because the toolCallId is missing or incorrect, or the JSON structure is invalid, it must return a results array with a matching toolCallId and a result string.

Thanks for all help

Checking if resolved..
