   > i,ll running zookeeper as docker-compose and running the basic helloworld demo.i donn`t edit any config file and just do anything as docs said.The server can running success but when i seed siginal and rerun the go-server then execute error.When i wana running go-client then said "providerConfig is nil!" and go-client exit. I'll check zookeeper and found provider was success registry to zk and consumer wasn't success registry. I check "dist/linux_amd64/release/go-client.log" found some param was set null,contains:
   > ?app.version=0.0.1&application=UserInfoClient&async=false&bean.name=UserProvider
   > &cluster=failover&environment=dev&generic=false
   > &group=
   > &interface=org.apache.dubbo.UserProvider
   > &ip=x.x.x.x
   > &loadbalance=
   > &methods.GetUser.loadbalance=
   > &methods.GetUser.retries=3
   > &methods.GetUser.sticky=false
   > &module=dubbo-go user-info client
   > &name=UserInfoClient&organization=dubbo.io
   > &owner=
   > &pid=11218&protocol=dubbo
   > &provided-by=
   > &reference.filter=cshutdown
   > &registry.role=0&release=dubbo-golang-1.3.0
   > &retries=
   > &side=consumer
   > &sticky=false&timestamp=1607913567
   > &version=
   > then i fix some param but another is still null and running exit,can everybody fix that problem?
   > i run at go-1.13.12

   * If you start ```go-client```, console print ```providerConfig is nil!``` is normal. After all, consumer doesn't need that config.
   * Consumer will shut down after call Provider, you can check the code as below
