RASA 3.0 socketio not working

Installed a fresh Rasa 3.0 and tried to connect from my website using socketio endpoint. I get this error

Exception occurred while handling uri: ‘http://localhost:5005/socket.io/?EIO=4&transport=polling&t=NrceI9f’ Traceback (most recent call last): File “handle_request”, line 83, in handle_request class Sanic(BaseSanic, metaclass=TouchUpMeta): File “/opt/anaconda3/lib/python3.8/site-packages/engineio/asyncio_server.py”, line 317, in handle_request return await self._make_response(r, environ) File “/opt/anaconda3/lib/python3.8/site-packages/engineio/asyncio_server.py”, line 385, in _make_response response = make_response( File “/opt/anaconda3/lib/python3.8/site-packages/engineio/async_drivers/sanic.py”, line 102, in make_response return HTTPResponse(body=payload, content_type=content_type, TypeError: ‘NoneType’ object is not callable

@medicareamaze what is your frontend and website?

I don’t think it’s a problem with OP’s frontend or website. It does not work even on localhost and using rasa’s chat widget. This issue has the details.
