Conditional Route in Phoenix, getting warning: no route path for AppWeb.Router matches “/”

Is this a bug? I’m seeing this error:

warning: no route path for AppWeb.Router matches “/”

mix phx.routes shows:

GET / AppWeb.RootController :call

and I have a conditional route in my router defined like this:

scope "/", AppWeb do
    pipe_through :browser
    get "/", RootController, :call
end

defmodule AppWeb.RootController do
  def init(opts), do: opts
  def call(conn, _opts) do
    if conn.assigns.current_member do
      AppWeb.MemberController.call(conn, :home)
    else
      AppWeb.PageController.call(conn, :home)
    end
  end
end

Can you share your entire router and the entire warning?

Rest of the router is the base generated one for phoenix + mix.phx.auth :

defmodule AppWeb.Router do
  use AppWeb, :router

  import AppWeb.MemberAuth

  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_live_flash
    plug :put_root_layout, {AppWeb.Layouts, :root}
    plug :protect_from_forgery
    plug :put_secure_browser_headers
    plug :fetch_current_member
  end

  pipeline :api do
    plug :accepts, ["json"]
  end

  scope "/", AppWeb do
    pipe_through :browser

    get "/", RootController, :call
  end

  # Other scopes may use custom stacks.
  # scope "/api", AppWeb do
  #   pipe_through :api
  # end

  # Enable LiveDashboard and Swoosh mailbox preview in development
  if Application.compile_env(:app, :dev_routes) do
    # If you want to use the LiveDashboard in production, you should put
    # it behind authentication and allow only admins to access it.
    # If your application does not have an admins-only section yet,
    # you can use Plug.BasicAuth to set up some basic authentication
    # as long as you are also using SSL (which you should anyway).
    import Phoenix.LiveDashboard.Router

    scope "/dev" do
      pipe_through :browser

      live_dashboard "/dashboard", metrics: AppWeb.Telemetry
      forward "/mailbox", Plug.Swoosh.MailboxPreview
    end
  end

  ## Authentication routes

  scope "/", AppWeb do
    pipe_through [:browser, :redirect_if_member_is_authenticated]

    live_session :redirect_if_member_is_authenticated,
      on_mount: [{AppWeb.MemberAuth, :redirect_if_member_is_authenticated}] do
      live "/members/register", MemberRegistrationLive, :new
      live "/members/log_in", MemberLoginLive, :new
      live "/members/reset_password", MemberForgotPasswordLive, :new
      live "/members/reset_password/:token", MemberResetPasswordLive, :edit
    end

    post "/members/log_in", MemberSessionController, :create
  end

  scope "/", AppWeb do
    pipe_through [:browser, :require_authenticated_member]

    live_session :require_authenticated_member,
      on_mount: [{AppWeb.MemberAuth, :ensure_authenticated}] do
      live "/members/settings", MemberSettingsLive, :edit
      live "/members/settings/confirm_email/:token", MemberSettingsLive, :confirm_email
    end
  end

  scope "/", AppWeb do
    pipe_through [:browser]

    delete "/members/log_out", MemberSessionController, :delete

    live_session :current_member,
      on_mount: [{AppWeb.MemberAuth, :mount_current_member}] do
      live "/members/confirm/:token", MemberConfirmationLive, :edit
      live "/members/confirm", MemberConfirmationInstructionsLive, :new
    end
  end
end

defmodule AppWeb.RootController do
  # import Plug.Conn

  def init(opts), do: opts

  def call(conn, _opts) do
    if conn.assigns.current_member do
      AppWeb.MemberController.call(conn, :home)
    else
      AppWeb.PageController.call(conn, :home)
    end
  end
end

For warnings I’m getting a bunch like this:

warning: no route path for AppWeb.Router matches "/"
  lib/app_web/member_auth.ex:84

warning: no route path for AppWeb.Router matches "/"
  lib/app_web/member_auth.ex:226
