我有这个消费者：

class TableConsumer(AsyncWebsocketConsumer):            
    async def connect(self):
        self.table_name = f'table_test'
        self.channel_name = f'channel_test'

        await self.accept()
        await self.channel_layer.group_add(
            self.table_name, self.channel_name
        )
        await self.manage_new_game_video()
            
    async def manage_new_game_video(self):                
        await self.channel_layer.group_send(
            self.table_name, {"type": "chat_message", "message": "message"}
        )

    # Receive message from room group
    async def chat_message(self, event):
        print("test")
        message = event["message"]

        # Send message to WebSocket
        await self.send(text_data=json.dumps({"message": message}))

由于某种原因，print语句永远不会执行，我不明白为什么。
为什么会这样呢？
谢谢。
