Help: TypeError: call() missing 2 required positional arguments: 'receive' and 'send'

Hi there,

I’m seeing the following error when utilizing this library with a Hypercorn server.

On project startup, I am seeing this error:

TypeError: __call__() missing 2 required positional arguments: 'receive' and 'send'

I can’t see exactly why this error is occurring, or what I have done wrong in my config setup…

return self.application_mapping[scope["type"]](scope)
web_1      | TypeError: __call__() missing 2 required positional arguments: 'receive' and 'send'

Relevant requirements.txt details:

channels==2.4.0
Django==3.1.4
django-channels-graphql-ws==0.7.5
Hypercorn==0.11.1
websockets==8.1

Update: this seems to be an issue with the required version of channels for this package. I forced an update to channels 3, and things seem to be working.

I suppose with an update to Channels 3 in v0.8.0 this should be addressed. Closing this. Feel free to reopen if the issue persists.
