I am wondering why the the callback doesn’t called during authenticating the user I tried to put some echo but there is no display.

my redirect url is like this

http://expense.x10host.com/home/expensex/public_html/web/site/




class SiteController extends Controller

{

    public function actions()

    {

        return [

            'auth' => [

                'class' => 'yii\authclient\AuthAction',

                'successCallback' => [$this, 'onAuthSuccess'],

            ],

        ];

    }


    public function onAuthSuccess($client)

    {

       $attributes = $client->getUserAttributes();


        echo "test";


        /** @var Auth $auth */

        $auth = Auth::find()->where([

            'source' => $client->getId(),

            'source_id' => $attributes['id'],

        ])->one();

        

        if (Yii::$app->user->isGuest) {

            if ($auth) { // login

                $user = $auth->user;

                Yii::$app->user->login($user);

            } else { // signup

                if (isset($attributes['email']) && isset($attributes['username']) && User::find()->where(['email' => $attributes['email']])->exists()) {

                        Yii::t('app', "User with the same email as in {client} account already exists but isn't linked to it. Login using email first to link it.", ['client' => $client->getTitle()]),

                    ]);

                } else {
