Enums in proto files fail.

See original GitHub issue

Testing enum types in proto messages I got the following errors:

https://github.com/maurogonzalez/rpctest/tree/enums

Using protocol.proto And srcGen to generate scala code.

grpc client returns:

ERROR:
  Code: Internal
  Message: grpc: failed to unmarshal the received message type_enum field HelloResponse.message is not compatible with nil value

mu client logs:

// ClientApp
 ...
client.sayHello(Test.HELLO)

// Server Log: INFO GreeterServiceHandler - Request: HelloRequest(GOODBYE)
// Client Log: INFO GreeterServiceClient - Request: HELLO - Result: HelloResponse(GOODBYE)

Not sure if it is related with Scala objects and Java’s io.grpc.

This issue should be fixed in the latest version (v0.20.1) of mu-scala. We’ve largely rewritten the protobuf serialization library and fixed a lot of bugs, as well as improving support for protobuf enums. The mu-scala codegen will now encode enums in Scala as enumeratum IntEnumEntrys, meaning the serialization library can serialize them to protobuf with the correct ordinal.

If you have any more problems with enums, please open a new issue.
