客户端连接断开了，找不到channel可以下发请求
The client end connection is disconnected, and the channel cannot be found to issue a request.

Check whether the application is restarting and publishing.

I guess that error message from this line

What about fix two minor things?

1. Chagne error message from "channel is error." to Unable to find the client's channel for response | responseBody: " + msg. I guess this issue is about cannot find channel context when response due to channel context from local context is deleted. Maybe the reason is application was restarted @slievrly mentiond. So i think message that i suggest might be more clear 😅

2. For clarity, refactor code using return early pattern

if (channel == null) { RuntimeException("") }
RpcMessage rpcMsg = buildResponseMessage(rpcMessage, msg, msg instanceof HeartbeatMessage
...
...

If these looks okay then I would create a PR.
