target server does not expose service xyz.XYZService

[laurijssen]

Consider the following message using an enum:

enum Provider {
Post = 0;
Call = 1;
}

message RequestMessage {
Provider provider = 1;
}

and compiling with

protoc -I/usr/local/include -I.
-I$(GOPATH)/src
-I$(GOPATH)/src/github.com/googleapis/googleapis
--descriptor_set_out=../proto/api_descriptor.pb
--go_out=plugins=grpc:../proto
--swagger_out=logtostderr=true:../swagger
--include_imports
--govalidators_out=../proto
*.proto

This works fine.

But after adding

import "github.com/mwitkow/go-proto-validators/validator.proto";

message RequestMessage {
Provider provider = 1 [(validator.field) = {is_in_enum : true}];
}

Now compile the same and the service becomes unaccessible over a grppc gateway:

Error invoking method "con.Service/New": target server does not expose service "con.Service"

This is a known issue I see now
