How can I debug my application?
The App Monitor, located under “Dev Tools,” allows you to find more information about requests that generated an error.
Under the Errors section you will see a list of all the times your application has seen this error message. Click on the message you want to inspect to see full details about the request, response type, and the calls where this error happened.
To debug errors associated with specific calls, Twilio records all responses received by your application in the Request Inspector. You can access the Request Inspector by navigating to your call logs and selecting a specific call.
The Request Inspector lists all requests made by Twilio. To view your application’s response to a particular request, expand the ‘Response’ subheading under the request.
