Programming Phoenix LiveView: error: redefine live_session (page 52-54)
I entered the code on page 52 establishing a new authenticated route and it won’t compile. I get:
$ iex -S mix phx.server
Compiling 1 file (.ex)
== Compilation error in file lib/pento_web/router.ex ==
** (RuntimeError) attempting to redefine live_session :require_authenticated_user.
live_session routes must be declared in a single named block.
(phoenix_live_view 1.0.0-rc.6) lib/phoenix_live_view/router.ex:274: Phoenix.LiveView.Router.__live_session__/3
lib/pento_web/router.ex:78: (module)
Looking in router, I see phx.gen.auth added another line with similar name
live_session :require_authenticated_user,
on_mount: [{PentoWeb.UserAuth, :ensure_authenticated}] do
live "/users/settings", UserSettingsLive, :edit
live "/users/settings/confirm_email/:token", UserSettingsLive, :confirm_email
end
Don’t know if that is issue or if it is something I’m doing wrong.
Any help appreciated.

Duh! Looking closer - it looks like same code. Maybe I was just supposed to add the one line to the lines already there instead of making a new block. Operator error on my part.
