Crash in redis/asyncio/connection.py using Django Channels

[developcreativo]

I'm encountering an issue when using Redis with Django Channels, where the connection crashes. Below are the details of my setup and an example of the code that's causing the issue:

Environment:

• Python version: 3.11.7
• Django version: 5.0.3
• Channels version: 4.1.0
• Channels Redis version: 4.2.0
• Redis version: 5.4.0
• Operating System: Ubuntu 20.04

Code Example:

from channels.generic.websocket import AsyncWebsocketConsumer

class ChatConsumer(AsyncWebsocketConsumer):
    channel_layer_alias = "chat"

    async def connect(self):
        user = self.scope["user"]
        if user.is_authenticated:
            # Accept the connection
            await self.accept()
            # Add the channel to a group with the current user's id
            await self.channel_layer.group_add(str(user.id), self.channel_name)

            on_websocket_connect_task.apply_async(
                kwargs=dict(channel_name=self.channel_name, user_id=str(user.id)),
                queue=settings.QUEUE_CHAT,
            )
        else:
            self.close(code=1000)

Error: The connection crashes in redis/asyncio/connection.py. Here is the traceback:

This error occurs repeatedly when the socket remains inactive for hours. It happens not only in the chat application but also in others. To connect to a socket, we have to attempt to connect up to 3 times.
