Handle asyncio.exceptions.CancelledError in custom connector

Rasa Open Source
1

Hello, RASA version: 3.0.8

I wrote a custom connector. If the response from the actions server takes more than 9 s then asyncio.exceptions.CancelledError is raised. Is it possible to extend this time when I await on_new_message? Also if the exception is catched and ok is returned from input channel, the rasa does not return response.

Here is the stack trace:

I know where is the problem. The client has a timeout set. Is it possible to return from webhook handler and run on_new_message in new thread.
