it is in app_web

def live_view do
quote do
use Phoenix.LiveView,
layout: {AppWeb.LayoutView, :live}

  unquote(view_helpers())                                                         
end

end

I’m not sure you can suppress this warning specifically but being that a deprecated usage you might want to change that before the next releases.

layout: {AppWeb.LayoutView, “live.html”}

must be replaced by

layout: {AppWeb.LayoutView, :live}

to remove the warning
