This seems to be your private plugin?

com.geely.cloud.sg.mgr.infra.integration.impl.EtcdRestClientImpl.getConfigsByPrefixPage

I don't think we could instrument com.geely.cloud package.

[wu-sheng]

We didn't know this, as this is totally internal etcd java client logic.
You need to debug grpc-java plugin in an using etcd app, and find out why the peer address is absent, then fix it.

address

I just upgraded the agent to the latest 9.5 version, but it still has the same error message！😭

[wu-sheng]

Then you need to debug on your own.
We can't debug plugins for all.

[dpzain]

think you so much ！i will debug grpc-plugin~（The local debug plugin is very troublesome.😖 Let me solve it）

[wu-sheng]

Learn remote debug of JDK. It is very convenient.
