yii2 hasOne relationship working error

Specific problem:

I have 2 tables: Users and Favorites:

users table
favorite

Copy after login

Now, I have a relationship in the "Favorites" model as shown below

public function getUser()
{
    return $this->hasOne(User::className(), [&#39;id&#39;, &#39;user_favorited&#39;]);
}

Copy after login

In the controller, I found List of user favorites

public function actionGetList()
{
    $favorite = Favorite::find()->where([
              &#39;user_favoriting&#39; => Yii::$app->user->id
          ])->all();
    foreach ($favorite as $key => $item) {
        # code...
        echo "<pre class="brush:php;toolbar:false">"; var_dump($item->user); echo "<br/>"; die(&#39;123&#39;);
    }
    return $favorite;
}

Copy after login

But when I request this operation, I get an error

Column not found: 1054 Unknown column &#39;0&#39; in &#39;where clause&#39;\nThe SQL being executed was: SELECT * FROM `users` WHERE (`0`, `1`) IN ((12, 80))",

Copy after login
