Usage example of GRPC is unclear

[sergei-pankratov]

Hi!

I launched openmock by running docker-compose and by setting OPENMOCK_GRPC_ENABLED and OPENMOCK_GRPC_PORT
Then I made a GRPC request to demo_probuf.ExampleService.ExampleMethod
Request timed out and I see following in logs:

     openmock         | {"error":"empty GRPCServiceMap","level":"error","msg":"failed to convert gRPC request body to JSON","time":"2021-02-18T06:42:30Z"}
     openmock         | {"grpc_host":"localhost:50051","grpc_method":"POST","grpc_path":"/demo_protobuf.ExampleService/ExampleMethod","grpc_req":"\u0000\u0000\u0000\u0000\u000e\u0008{\u0012\u0006fooBar\u001a\u0002{{","grpc_res":"{\"message\":\"Internal Server Error\"}\n","level":"info","msg":"","time":"2021-02-18T06:42:30Z"}

I tried to find what that error means in source code and the only place where GRPCServiceMap is assigned is in /grpc_test.go
Does that mean that currently in order to use GRPC mocking one has to write a Go wrapper project?

Thanks!

Sidenote: I'd like to say that it took me some time to find out that one has to enable GRPC by setting OPENMOCK_GRPC_ENABLED
At first I just set OPENMOCK_GRPC_PORT and expected it to work 😅 since a Kafka configuration example which is a few lines below mentions OPENMOCK_KAFKA_ENABLED flag. Perhaps Readme.md should mention OPENMOCK_GRPC_ENABLED

@tehnetaholic Hi! Did you find a workaround? I'm getting the same error with two console clients
