      $dataproviderTest = new ArrayDataProvider([
                    'allModels' => $array,
                    'sort'=>[
                    'attributes'=>['Conference','CallerIDNum','CallerIDName',]],

      $gridColumns = [
            ['class' => 'yii\grid\SerialColumn'],
                'Conference',
                [
                    'attribute' => 'CallerIDNum',
                    'label' => 'Caller Number',
                ],
                [
                    'attribute' => 'CallerIDName',
                    'label' => 'Caller Name',
                ],

        ];

        // Renders a export dropdown menu
        echo ExportMenu::widget([
            'dataProvider' => $dataproviderTest,
            'columns' => $gridColumns
        ]);

        // You can choose to render your own GridView separately
        echo \kartik\grid\GridView::widget([
            'dataProvider' => $dataproviderTest,
           // 'filterModel' => $searchModel,
            'columns' => $gridColumns
        ]);

I have installed the widget and also tried different ways to fix this like reinstal steps given in some forums.

But still having the following error.

I have tried different widget from kartik but no luck to use them fully.
