django channels websocket asyncio Python

This might be a silly question, but I'm working on a Django application using Django Channels (version 3.1) to handle WebSocket connections, and I'm experiencing an scenario where my WebSocket consumer does not seem to receive messages sent to a group. I have a simple chat application set up, and while I can successfully connect and disconnect clients, messages sent to the group do not arrive at the consumers. Here's a snippet of my consumer code: ```python from channels.generic.websocket import AsyncWebsocketConsumer import json class ChatConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_name'] self.room_group_name = f'chat_{self.room_name}' await self.channel_layer.group_add( self.room_group_name, self.channel_name ) await self.accept() async def disconnect(self, close_code): await self.channel_layer.group_discard( self.room_group_name, self.channel_name ) async def receive(self, text_data): text_data_json = json.loads(text_data) message = text_data_json['message'] await self.channel_layer.group_send( self.room_group_name, { 'type': 'chat_message', 'message': message } ) async def chat_message(self, event): message = event['message'] await self.send(text_data=json.dumps({ 'message': message })) ``` In my routing configuration, I have: ```python from django.urls import re_path from . import consumers websocket_urlpatterns = [ re_path(r'ws/chat/(?P<room_name>[^/]+)/$', consumers.ChatConsumer.as_asgi()), ] ``` Additionally, I'm using Redis as my channel layer backend and have configured it in my settings.py like this: ```python CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [("127.0.0.1", 6379)], }, }, } ``` I've tried running the Redis server and verified that it's running with no issues. However, when I send messages from the client, I see no errors in the console, but the messages do not reach other connected clients in the group. I've also verified that the `room_name` is correctly passed in the WebSocket connection. Any ideas on what could be going wrong? I've checked the documentation and need to find anything that stands out as a potential mistake. I'm hoping someone with more experience in Django Channels can guide to troubleshoot this scenario. This is happening in both development and production on Windows 10.
