Failed to run custom action 'action_default_fallback'. Action server responded with a non 200 status code of 500. Make sure your action server properly runs actions and returns a 200 once the action is executed. Error: 500 Server Error: INTERNAL SERVER ERROR for url: http://localhost:5055/webhook

On your Action server, you should see stack trace of why it return 500. Do you have log for that?
