Ash.update Not Passing Actor down to `after_action/3` change

Hi all,
I am getting a strange behaviour where Ash.update is not passing the context’s actor down the change after_action(&ProcessApproved.run/3), but when I call the same action through the code interface it works.

What could I be doing wrong?

This doesn’t work

    context = %{actor: user, tenant: user.current_tenant, authorize?: false}

    step
    |> Ash.Changeset.for_update(:approve, %{actor_remarks: "Test Remarks"})
    |> Ash.Changeset.set_context(context)
    |> Ash.update()

But this works

    context = [actor: actor, tenant: actor.current_tenant, authorize?: false]
    Approvals.approve_step!(step, %{actor_remarks: remarks}, context)

Resource Action definition

    update :approve do
      accept [:actor_remarks]

      require_atomic? false
      filter expr(status == :pending)
      change set_attribute(:status, :approved)
      change after_action(&ProcessApproved.run/3)
    end

after action fun definition

defmodule ProcessApproved do
  def run(_changeset, step, context) do
    dbg(context)
    {:ok, step}
  end

Output of the dbg(context)

   context #=> %Ash.Resource.Change.Context{
      actor: nil,
      tenant: "tenant_name",
      authorize?: true,
      tracer: nil,
      bulk?: false
    }
