[Bug]: Server throw Error 500 on listener_run call

What happened?

Sometimes we just got an error 500 from the server when calling a listener from the app.

Probably when the listener return nothing or crash, the listener get a timeout error and made this error to be thrown.

What browsers are you seeing the problem on?

Start by reproducing a listener_run call where the listener returns nothing or crashes, then trace the stack through lib/services/application_services.ex response/2 and run_listener/5 and lib/event_handler.ex handle_call/3. Compare the resulting timeout or failure with the expected listener response and document or test the behavior that should replace the generic 500 error.
