I wanted to get really adventurous - and - tried to create a new application with the latest and greatest versions of Phoenix & Phoenix LiveView. So I used

{:phoenix, github: "phoenixframework/phoenix", override: true},
{:phoenix_live_view, github: "phoenixframework/phoenix_live_view", override: true},

When I did a mix deps.get, I got an error saying phoenix_html is diverging. Then I replaced

{:phoenix_html, github: "phoenixframework/phoenix_html", override: true},

Now, the deps are correctly installed. However, when I run, mix phx.server I am getting an error unknown live option :session in file router.ex
Any work arounds?

Hi!

Is this the error you’re getting?

== Compilation error in file lib/hello_web/router.ex ==
** (ArgumentError) unknown live option :session.

Supported options include: :container, :as, :metadata, :private.

Got: [session: {Phoenix.LiveDashboard.Router, :__session__, [nil, false, {HelloWeb.Telemetry, :metrics}, nil, [], nil, nil, nil]}]

Switching phoenix_live_dashboard to the current unreleased version as well seems to be fixing it for me:

{:phoenix_live_dashboard, github: "phoenixframework/phoenix_live_dashboard", override: true},

Also, you probably did this as well, but for anyone else reading this: for trying out new unreleased phoenix versions it’s good to use the installer from phoenix master. You can install it by following instructions from README.md in the installer directory
