Error Starting GRPC.Server.Supervisor with Phoenix 1.7.0-rc-0

[cdesch]

Describe the bug Following the helloworld example and adding it to a Phoenix 1.7.0-rc-0 application, I get the following Error:

** (Mix) Could not start application phx_one_seven_grpc: PhxOneSevenGrpc.Application.start(:normal, []) returned an error: shutdown: failed to start child: GRPC.Server.Supervisor
    ** (EXIT) an exception was raised:
        ** (FunctionClauseError) no function clause matching in GRPC.Server.Supervisor.init/1
            (grpc 0.5.0) lib/grpc/server/supervisor.ex:41: GRPC.Server.Supervisor.init([endpoint: Helloworld.Endpoint, port: 50051])

            (stdlib 3.17) proc_lib.erl:226: :proc_lib.init_p_do_apply/3

To Reproduce Steps to reproduce the behavior:

1) Clone this repo phx_one_seven_grpc which contains the Phoenix 1.7.0-rc-0 project with elixir-grpc installed. 2) Run iex -S mix to run the Phoenix Server 3) Error will reproduce

Expected behavior ~A clear and concise description of what you expected to happen.~

Expected that the grpc server will start with Phoenix

Things should work if you use the github master branch instead of the Hex 0.5.0 version. Basically, we deprecated the global environment config in favor of a options-based config.

The issue is that you are using the new way in you application tree, but the code expects the old way.

Thanks for the report!

[cdesch]

You're welcome. So, just reference

{:grpc, git:  "https://github.com/elixir-grpc/grpc"}

for now instead of the following?

{:grpc, "~> 0.5.0"},

Is the plan for this change to be released in 0.6.0 ?

[polvalente]

You can either reference git or follow the instructions for 0.5 instead and it should be good to go.

Yes, everything after 0.5 on main will be eventually released on 0.6 :)
