This code is intended to validate a user typed DELETE before deleting their account, but it doesn’t work because add_error isn’t adding the error nor making the changeset valid?: false. Perhaps the issue might be that it’s run inside before_action which was needed so that the validation doesn’t happen until form submission. What’s the right way to accomplish this? Thanks.

  change fn changeset, _ ->
    Ash.Changeset.before_action(changeset, fn changeset ->
      if Ash.Changeset.get_argument(changeset, :confirm_word) == "DELETE" do
        changeset
      else
        changeset
        |> Ash.Changeset.add_error(
          field: :confirm_word,
          message: "Type DELETE to confirm"
        )
      end
    end)
  end
