Filter in resourceless update not making changes after Ash 3.4.29

[haste]

Describe the bug

After upgrading to Ash 3.4.29 one of our update actions have stopped updating.

To Reproduce

The relevant code is the logout action in lib/helpdesk/account/user_session.ex:

    update :logout do
      change filter expr(session_uid == ^actor(:session_uid))
      accept []
      change set_attribute(:user_id, nil)
    end

Full minimal reproduction project: https://github.com/haste/ash_filter_in_resourceless_update_bug Run mix test.

Downgrading Ash to 3.4.28 makes the test pass.

Expected behavior

Expected behavior is for the action to run a SQL UPDATE statement setting user_id to null.

Runtime

• Elixir version 1.17.3-otp-27
• Erlang version 27.1.2
• OS Fedora Linux 40
• Ash version 3.4.29
• any related extension versions

Additional context

This was initially reported on the Elixir slack

This appears to have already been fixed in latest main of ash and ash_postgres. As such, I will close this. Those will be released this week.
