@User - I'm creating a custom tool (function), and am receiving this error: Network error: Unable to connect to the server. This could be due to CORS restrictions, the server being down, or network connectivity issues. I've checked everything I can think of, have specifically added CORS responses to my server for OPTIONS requests, and can see that your system is requesting OPTIONS from my server, and getting a response. Is there any way I can view the request being sent, and the response, from VAPI's end, so I can figure out the real problem?

Ensure your server returns Access-Control-Allow-Origin, Methods, and Headers. To debug, use Vapi client.logs.get() to view request/response logs, or check your dashboard and browser dev tools for more insights.

Right now, I'm using the vapi web dashboard to build and running test requests from there. Where would I find the logs in there?

Go to your dashboard, then go to the Calls tab to view detailed logs and analyze individual test requests.

Just set your express server to allow all origins
