Hi Rehan, Let's address each of your issues: 1. Tools Not Returning Responses: If the assistant triggers the tools but doesn't relay the responses, check the following: - Ensure that the system prompt explicitly describes how to process and output tool responses. - Verify that the API logs in the Vapi dashboard show the correct request and response from the tool. A [review of the API Logs](https://docs.vapi.ai/debugging#api-logs) might help identify any discrepancies. - Confirm that the webhook integration with Make.com correctly sends the response back to Vapi and that the response format matches what the assistant expects. 2. Assistant Not Found: When the "Talk to Assistant" button indicates the assistant could not be found, check: - If the assistant has been published correctly in the dashboard. Go to the Assistants section, ensure your setup is complete, and click "Publish" if required. - Verify that there are no configuration errors or missing fields by reviewing the assistant's settings and ensuring all necessary fields are filled in. 3. Upgrade Requirements: With the new Vapi upgrades, workflow and tool configurations might need adjustments: - Ensure that you're using the updated workflow configuration available in the [Vapi Guides on workflows](https://docs.vapi.ai/examples/pizza-website), which can provide insights into setting up your workflow following recent changes to the platform. For further assistance, reviewing the specific call or API logs and ensuring your configuration aligns with current setup guidelines would be beneficial.
