Cast error when missing operation

[lud-wj]

     ** (UndefinedFunctionError) function :ok.operationId/0 is undefined (module :ok is not available)
     code: |> get("/my/route")
     stacktrace:
       :ok.operationId()
       (open_api_spex 3.17.3) lib/open_api_spex/plug/cast_and_validate.ex:124: OpenApiSpex.Plug.CastAndValidate.call/2
       

This happens because I have plug CastAndValidate, render_error: FallbackController but I forgot to declare the operation for some route.

I guess it should throw an explicit exception or maybe just let the request pass.

Looks slightly similar to #447
You can use the following to silence such errors, but it does make to raise a more informative exception.

operation :some_action, false
def some_action(...) do
end
