I’m using the elixir version 1.15.8, erlang 25.3.2.12 and Phoenix.LiveDashboard.Router. Here is my router.ex

pipeline :member_graphql do
    plug(Plug.Telemetry, event_prefix: [:myapp, :member_graphql_http])
    plug(:default_parser)
    plug(:fetch_session)
    plug(:accepts, ["json"])
    plug(MyApp.Authenticator, except: ["/graphql", "/member/graphql"])
end
scope "/member/graphql" do
    pipe_through(:member_graphql)
    post("/", Absinthe.Plug,
      schema: MyApp.Schema,
      json_codec: Jason,
      pipeline: {Opencensus.Absinthe.Plug, :traced_pipeline}
    )
end`

I got the error: Request: POST /member/graphql ** (exit) an exception was raised: ** (UndefinedFunctionError) function Opencensus.Absinthe.Plug.traced_pipeline/2 is undefined or private (opencensus_absinthe 0.2.0) Opencensus.Absinthe.Plug.traced_pipeline

When I use elixir 1.14.5. It works fine. But elixir v1.15.8, it’s failed. Could you please give me idea or suggestion to fix this error.

This might be related to load path pruning introduced in 1.15. Check Elixir v1.15 released - The Elixir programming language, the “Compile and boot-time improvements” and see if the suggested config change helps you.
