Hello,
I was working on a grpc server based project, I have a proto which has
updated through different versions. As I was testing my server from
different aspect. It was evident that when a call is made on server from a
older version of proto, server throws error:

While the client gets error
io.grpc.StatusRuntimeException: UNKNOWN
I want the client side error to be more descriptive as why the call failed
and what proto to use .I tried interceptor for catching the error, but the
error does not get catch by interceptor. Is there any way to catch this
error and modify the error for proper error handling.
PS. The Sample two proto verions are
Version 1.0:
service EchoService {
rpc Echo(SimpleMessage) returns (SimpleMessage) {}
}
message SimpleMessage {
string id = 1;
}
Version 2.0:
service EchoService {
rpc Echo(SimpleMessage) returns (SimpleMessage) {}
}
message SimpleMessage {
int64 id = 1;
}
