I have connected Twilio to my basic Rasa chatbot using CALM. The call connects but immediately hangs up. When I inspect ngrok, the call is received by Rasa, the session_start message is triggered but there appears to be no content and Rasa returns a 200OK with an empty body.
I am been searching documentation and using the basic Text tutorial to keep it simple. Rasa seems to be working fine with text based communication.
I have attached details from inspector and debug log.
Any ideas how to fix this would be much appreciated.
