My user resource thas the following relationship:

    many_to_many :schools, School do
      through UserSchool
      join_relationship :user_schools

      source_attribute_on_join_resource :user_id
      destination_attribute_on_join_resource :school_id
    end

In my School resource, I have the following policy:

  policies do
    alias School.Checks

    policy always() do
      authorize_if Checks.IsConfirmed
    end
  end

And the IsConfirmed check is implemented as this:

defmodule Core.Ash.Checks.IsConfirmed do
  @moduledoc false

  use Ash.Policy.SimpleCheck

  def describe(_), do: "actor account is confirmed"

  def match?(%{confirmed_at: nil}, _, _), do: false
  def match?(%{confirmed_at: _}, _, _), do: true
end

After upgrading to Ash 3.0, when I try to sign-in using the sign_in_with_password action, the actor field from match?/3 always arrive as nil which will fail the match of the check.

Did something changed that I need to update to make this work again? I check both Ash upgrade guide and Ash authentication one but didn’t find anything that would help.
