I got the answer. I am sharing the answer here so that anyone having this
problem can use this. Thank you.
First solution is change the rpc call from
rpc Hello(HelloRequest) returns (HelloResponse){} to rpc
Hello(HelloRequest) returns (ServerInfo){}. This will work.
Second solution is when we have an obligation to not to change the rpc call
then in server we can use the below code to call the ServerInfo fields and
assign them to HelloResponse.
ServerInfo* serverinfo=new ServerInfo();
serverinfo->set_name("");
serverinfo->set_os("");
serverinfo->set_arch("");
serverinfo->set_nproc("");
HelloResponse* res;
res->set_allocated_server(serverinfo);
