### Describe the Bug

I got an inexplicable error. I just started and waited for messages, did nothing, and suddenly an error occurred. I caught it. I am not sure whether I need to ignore this error. It looks more like a bug or a problem that should not exist. It will interrupt my program.

### Steps to Reproduce

Start and run the following code in the Nest program, and then try to send a few messages. It should be normal at this time.
Then we wait patiently for a while. This error will not be triggered in a short time. It seems that there is a scheduled task that changes some status. In short, we have to wait for a long time.

If nothing goes wrong, you should wait until the program has an error:

```

This error comes from StatusChecker.check(status) in the receiveMessage method.

This error indicates that when calling RocketMQ to receive messages, Settings.getSubscription() returned null, causing a NullPointerException.

Why does the Subscription data in Settings suddenly disappear? Why does the NullPointerException exist?

### What Did You Expect to See?

Continuous, continuous and normal operation

### Additional Context

_No response_

Start at org.apache.rocketmq.proxy.grpc.v2.consumer.ReceiveMessageActivity.receiveMessage(ReceiveMessageActivity.java:63) and trace how the request reaches StatusChecker.ts:81, Consumer.ts, and SimpleConsumer.ts. Reproduce the long-running receive scenario from the NestJS example and determine why the Settings value becomes null; done means continuous receiving no longer produces this NullPointerException.
