[Bug]: proxy warning log ["status is nil, please fix it"] for query node

[hwc1824]

Is there an existing issue for this?

• [X] I have searched the existing issues

Environment

- Milvus version: v2.4.4
- Deployment mode(standalone or cluster): cluster
- MQ type(rocksmq, pulsar or kafka): pulsar
- SDK version(e.g. pymilvus v2.0.0rc2): v2.4.0
- OS(Ubuntu or CentOS):  
- CPU/Memory: 
- GPU: 
- Others: Hosted in K8s

Current Behavior

Though searching on collections, loading / releasing collection are working fine, all the proxy pod showed this warning message repeatedly, I tried to rolling restart the proxy and querynode but it didn't get resolved.
