@Moe I'm sorry to hear that you're experiencing issues with your VAPI integration. Let's try to troubleshoot the problem step by step. First, please ensure that your Ngrok agent is running and that you have copied the correct Ngrok forwarding URL to your VAPI integration settings. If the Ngrok URL has changed or the agent is not running, VAPI will not be able to send POST requests to your server. If you've confirmed that the Ngrok agent is running and the URL is correct, we should check if there are any issues with the VAPI events or the configuration of your custom LLM within Voiceflow. Could you please verify the following: 1. The Ngrok URL is correctly set in the VAPI integration settings. 2. The Ngrok agent is active and has not encountered any errors. 3. The custom LLM is properly configured in Voiceflow and is set to handle the assistant ID you provided. If you've checked all of the above and the issue persists, it might be necessary to look into the VAPI event logs for any errors or to check the configuration on the Voiceflow side for any discrepancies. If you need further assistance with checking the event logs or configurations, please let me know, and I'll be happy to help. If you believe there might be an issue with the VAPI service itself, you may need to reach out to VAPI support for more detailed investigation.
