Django Channels: Channel Name type error appears when loading web socket chat-CodePudding

I'm building a basic websocket live chat using Django Channels and while the site loads fine, when I enter into the site, in my terminal I get this TypeError Message:

TypeError: Channel name must be a valid unicode string with length < 100 containing only ASCII alphanumerics, hyphens, underscores, or periods, not RedisChannelLayer(hosts=[{'host': '127.0.0.1', 'port': 6379}])

Im assuming the problem lies in my settings.py file but based on my current channel layer settings, I don't see what the problem is:

CHANNEL_LAYERS = {
    'default': {
        "BACKEND": 'channels_redis.core.RedisChannelLayer',
        "CONFIG": {
            "hosts": [('127.0.0.1', 6379)],
        },
    },
}

I'm new to django and channels so maybe there's a place where I defined the channel name and i'm just missing but I'm not sure or where to look for it if thats true.

This is my Full traceback error and consumer.py file btw:

Exception inside application: Channel name must be a valid unicode string with length < 100 containing only ASCII alphanumerics, hyphens, underscores, or periods, not RedisChannelLayer(hosts=[{'host': '127.0.0.1', 'port': 6379}])

CodePudding user response：

You should pass self.channel_name to group_add() and not self.channel_layer

    async def connect(self):
        self.roomGroupName = 'group_chat_gfg'
        await self.channel_layer.group_add(
            self.roomGroupName,
            self.channel_name # here
