Debugging your Function

Console Debugging

If you are actively working on your Function then all invocation and logs will stream to your browser in near-realtime. Here's an example:

✗ curl https://my-domain-1234.twil.io/log-demo?arg=value 

Functions console.log example

As you can see, Twilio Functions streamed the start, end and console.log output of my function into the Twilio console.

Monitoring for failures

If your Function returns an error in response to a Twilio Webhook then you will find this under the Debugger. Note: The debugger also supports searching by URL, so you could search for all errors/warnings relating to your function.
