I tried to render a view, but I got this error

pagination.PNG

Controller




    public function actionAvailableCoursesGroupings()

    {

        $user = Yii::$app->getid->getId();

        $instructorSession = Yii::$app->session->get('instructor_id');        


        $searchModel = new CoursesSearch();

        $dataProvider = $searchModel->searchcoursegroupings(Yii::$app->request->queryParams, $user);

        $dataProvider->pagination->pageSize=3;


        return $this->render('available-courses-groupings', [

            'searchModel' => $searchModel,

            'dataProvider' => $dataProvider,

        ]);         

    }

What do I do that this error won’t come up even if its empty

Thanks
