What did you do?

We use gRPC in our product (thank you for it). Our testers reported a bug that one of the APIs didn’t work.

What did you expect to see?

Working rpc.

What did you see instead?

"Did not read entire message","grpc_status":13"

For no reason we faced the error ^^ above. I did some investigations and figured out that the issue could be fixed simply by the variables re-ordering in that particular message.

Sample application

I’ve written a sample application to confirm the bug https://github.com/AntonQubecinema/grpc-issue. Please refer to README for the details.
