How to read grpc command line tool error messages from the responses?

[Sanket Lawangare]

I am using the grpc command line tool to test response for my request. This is the official link to the grpc command line tool: https://github.com/grpc/grpc/blob/master/doc/command_line_tool.md

In the response I am getting it says that there are some errors however, it does not show what the errors are. Here is the response I got from my client request:  

Failed to read response.

Rpc failed with status code 12 error message unknown service my_agent.MyServiceAPI 


I am running the command from the location where my protocol file resides. I am sending a request like this, (FYI: I am also sending the metadata. Irrespective of including the metadata or not I am getting the same error message) : 

~/my_workspace/src/github.com/grpc/bins/opt/grpc_cli call 0.0.0.0:50051 MyGrpcMethod <name_of_my_proto_file.proto> "abc : '12-34-56-78', xyz: '1234'" --metadata "auth:<auth_token>:space:xxx:org:xxx" --enable_ssl=false

You did get error information: "Rpc failed with status code 12 error message unknown service my_agent.MyServiceAPI " The part that says "unknown service my_agent.MyServiceAPI" means that the server does not have an implementation of a service with that name, and status code 12 means "unimplemented". This probably means that either your server is misconfigured or that you are not using the right proto file in your grpc_cli invocation.

Did you ever figure it out? I would love to know! I'm running into the same problem.

Apologies for the shameless plug, but another option would be to try polyglot from the grpc-ecosystem. Based on the example call made in the thread above, it seems that polyglot has all the required features.
