Hello community!

I encounter a warning saying that AshAuthentication.Errors.AuthenticationFailed does not implement the AshPhoenix.FormData.Error protocol while running tests (with an voluntary wrong password) for a Phoenix Liveview.

...12:06:14.730 [warning] Unhandled error in form submission for Prepair.AshDomains.Accounts.User.change_password

This error was unhandled because AshAuthentication.Errors.AuthenticationFailed does not implement the `AshPhoenix.FormData.Error` protocol.

** (AshAuthentication.Errors.AuthenticationFailed) Authentication failed

I’ve read this issue: This error was unhandled because it did not implement the `AshPhoenix.FormData.Error` protocol. · Issue #516 · ash-project/ash · GitHub and tried the proposed solution, but it didn’t worked for me.

Here is my change_password action:

update :change_password do
      # Use this action to allow users to change their password by providing
      # their current password and a new password.

      require_atomic? false
      accept []
      argument :current_password, :string, sensitive?: true, allow_nil?: false

      argument :password, :string,
        sensitive?: true,
        allow_nil?: false

      argument :password_confirmation, :string,
        sensitive?: true,
        allow_nil?: false

      validate confirm(:password, :password_confirmation)

      validate {AshAuthentication.Strategy.Password.PasswordValidation,
                strategy_name: :password, password_argument: :current_password}

      change {AshAuthentication.Strategy.Password.HashPasswordChange,
              strategy_name: :password}
    end

I tried to add change set_context(%{strategy_name: :password}) before the other change call, but it didn’t solved the warning.

Here are the current uses and imports on my resource:

defmodule Prepair.AshDomains.Accounts.User do
  use Ash.Resource,
    domain: Prepair.AshDomains.Accounts,
    data_layer: AshPostgres.DataLayer,
    authorizers: [Ash.Policy.Authorizer],
    extensions: [AshAuthentication]

  alias Prepair.AshDomains.Profiles.Profile

  import Prepair.AshDomains.ValidationMacros

Here are the current uses and imports in my domain (which exposes the code interfaces then used in the liveview).

I wonder if I should add AshPhoenix there.

defmodule Prepair.AshDomains.Accounts do
  use Ash.Domain

And here is my handle_event function for the save action in the Liveview:

def handle_event("save", %{"user" => params}, socket) do
    current_user = socket.assigns.current_user

    form =
      AshPhoenix.Form.for_update(current_user, :change_password,
        domain: Accounts,
        as: "user"
      )
      |> AshPhoenix.Form.validate(params)

    case AshPhoenix.Form.submit(form, params: params) do
      {:ok, _user} ->
        {:noreply,
         socket
         |> put_flash(:info, "Password updated successfully")
         |> redirect(to: ~p"/")}

      {:error, form} ->
        {:noreply,
         socket |> assign(:form, to_form(form)) |> assign(check_errors: true)}
    end
  end
