You can pass uvicorn arg to gunicorn by making your own worker like this:

from uvicorn.workers import UvicornWorker

class DjangoUvicornWorker(UvicornWorker):
    CONFIG_KWARGS = {
        "loop": "uvloop",
        "http": "httptools",
        "lifespan": "off",  # lifespan is not handled by django channels for now
        "ws": "wsproto",
    }

Then use this as your --worker-class

The bus is fixed installing wsproto and using it with the command --ws wsproto

How did you set --ws wsproto for gunicorn?
