GRPC Reflection server on 2.11.0-beta.1

[genhoi]

I tried the new RoadRunner beta (2.11.0-beta.1) for GRPC Reflection for Postman and GrpcUI, for some reason it didn't work for me, is there any way to tell me what I'm doing wrong?

I added a flag to the settings to enable.

RR log output:
[INFO] RoadRunner server started; version: 2.11.0-beta.1, buildtime: 2022-07-18T14:43:58+0000

Postman output:

grpcui output:

docker compose logs grpcui
grpcui-1  | Failed to compute set of methods to expose: Symbol not found: utp.catalog_write.v1.CatalogWriteService

Although the methods themselves work, if you call the GRPC methods at this address

EDIT: issue: #1208

Hey @genhoi 👋🏻
Yeah, this is a known problem. You should specify a proto file to have this feature working. We are working on fixing that. Thanks for the report 👍🏻

[genhoi]

Here are the details:

My import proto path /app/proto/utp, but RR does not know about it and there is no setting to tell RoadRunner about it

[genhoi]

@rustatian I suggest adding the proto_path setting to the grpc settings section, relative to which to search for proto files to import

Like this:

grpc:
  listen: "tcp://0.0.0.0:${RR_GRPC_PORT}"
  enable_reflection_server: true
  proto_path: "/app/proto/utp"
  proto:
    - "/app/proto/utp/catalog_write/catalog_write_service.v1.proto"
  pool:
    num_workers: ${RR_GRPC_WORKERS_COUNT}
    debug: ${RR_GRPC_WORKERS_DEBUG}

Or maybe there is another solution without modifying the code

[rustatian]

@genhoi Thanks for the feedback. We already parse the protofiles; we have the ability to include imports to the protoc includes to have full protodefinitions for the reflection server.

@genhoi Hey 👋🏻 Could you please try rc.1 release and new configuration for the reflection server?
https://github.com/roadrunner-server/roadrunner/releases/tag/v2.11.0-rc.1

[genhoi]

I tried the new version with this configuration

grpc:
  listen: "tcp://0.0.0.0:${RR_GRPC_PORT}"
  reflection_server:
    include: []
  proto:
    - "/app/proto/utp/catalog_write/catalog_write_service.v1.proto"
  pool:
    num_workers: ${RR_GRPC_WORKERS_COUNT}
    debug: ${RR_GRPC_WORKERS_DEBUG}

but RR does not start

Reflection was removed. Any reason?
