I am getting daphne internal server error 500

I also cant use redis 😦 what should I do

a similar error I found was https://github.com/django/channels/issues/1035

[andrewgodwin]

You don’t need a channel layer, unless you want to talk between different consumers. But if you need one, Redis is the only one we maintain.

[andrewgodwin]

Hey, I’m afraid this issue tracker is for specific, reproduceable bugs, not general support requests - see https://channels.readthedocs.io/en/latest/support.html for where you should ask those.

In particular, you shouldn’t be setting an InMemoryChannelLayer for production usage, it’s for testing only.
