我是3.1.11也遇到了这个问题
org.apache.dubbo.rpc.RpcException: Failed to invoke the method
getUserByUserId in the service
com.moree.usrcenter.facade.service.UcUserFacadeV2. Tried 1 times of the
providers [10.244.6.42:20902] (1/2) from the registry nacos-master:8848 on the
consumer 10.244.21.191 using the dubbo version 3.1.1. Last error is: Failed to
invoke remote method: getUserByUserId, provider:

org.apache.dubbo.remoting.RemotingException: Server side(10.244.6.42,20902)

dubbo://10.244.6.42:20902!
看起来
org.apache.dubbo.config.metadata.ConfigurableMetadataServiceExporter#buildServiceConfig
这个方法中写死了

我看了3.2.0里面没有这个问题了,先扩容一下机器,回头升级3.2.0.
