This part of the error log seems most relevant. It states that the socket
closed and the connection is no longer valid. I don't understand why this
is the case as the grpc::ClientReaderWriter object is still active after
the Read/Write requests are done?

Any idea what could be wrong with the code to cause this error?
Thanks,
