cakephp4 ログイン認証機能について

Question

現在私はcakephp4でログイン認証機能を作ろうと試みております。

cakephp4
Authentication 2.0

参考にしたサイト↓↓↓↓↓↓↓↓↓↓
シンプルな認証と認可のアプリケーション

ログインページから名前とパスワードを入力しログインしようとすると、

Table class for alias Users could not be found.

エイリアスUsersのテーブルクラスが見つかりませんでした。

というようなエラーメッセージが吐かれます。
このエラーメッセージで検索を行いましたが見当はずれのサイトばかりなのか自分の理解力がないのかで全く参考になるサイトがありませんでした。このエラーメッセージの原因と打開策をご教授お願い致します。

自身の見解は、controllerphpのlogin関数でlogメソッドで確認したところ

Argument 1 passed to Cake\Controller\Controller::log() must be of the type string, object given, called in /var/www/html/sample/src/Controller/ContactsController.php on line 163

というエラーメッセージが吐かれていたのでlogin関数の$resultになにもデータが入っていないことが原因だと考えていますがどこが問題でデータがとれていないのでしょうか？
宜しくお願い致します。

Answer 1

$authenticationService->loadIdentifier('Authentication.Password', [

  'resolver'=>[
    'className' => 'Authentication.Orm',
    'userModel' => 'Contacts'
],
    'fields' => [
        'username' => 'mail',
        'password' => 'password',
    ]
]);

これでできました
