"An application error has occurred” error on your call

An application error means that the code Twilio is attempting to fetch at the URL that you have specified on your servers is either unavailable or has errors in it. This code is being fetched based on the incoming URL that you have specified on your phone number or in your application for instructions on how to handle a call.

To handle an error like this, you should view your Twilio project's debugger logs for details on the errors your application is running into.
