protoc-gen-json: options are omitted

[srenatus]

When looking at the protoc-gen-json output of

protoc -I. -Ivendor/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis/ --json_out=$(pwd)/out components/automate-gateway/api/iam/v2beta/policy.proto

run with this file, I see most of what I'd expect to see, but all the options fields a empty. For example,

      "service": [
        {
          "name": "Policies",
          "method": [
            {
              "name": "CreatePolicy",
              "input_type": ".chef.automate.api.iam.v2beta.CreatePolicyReq",
              "output_type": ".chef.automate.api.iam.v2beta.CreatePolicyResp",
              "options": {}
            },

Am I missing something? Is there a way to have the options dumped as well? I do believe all the information should be in the CodeGenerationRequest 🤔

Hah it's probably what was noted here:

If you wish to retain e.g. grpc-gateway google.api.http annotations, you'll need to make use of protoc-gen-dump instead of protoc-gen-json.

Sorry for the noise. 😄

At any rate, I'm still curious what an annotation needs to do to be json-encodable... Can you enlighten me? 😃
