Alright, I'll provide the test cases to you later.

Let me briefly describe the issue first. After using the Redis adapter, when calling socket.To().FetchSockets, if the room doesn't exist on the other server or there are no sockets connected to it, the sockets return value will be empty. In this case, the receiver chooses to ignore it directly, potentially failing to trigger the callback correctly and causing a timeout.
