Я не могу отобразить свой yajrabox-datatable в моем представлении.Я получаю следующую ошибку:
DataTables warning: table id=dataTableBuilder - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1
Я установил расширенный класс datatables и включил return $dataTable->render('activities/index'); в свой контроллер.

Log::info('Source: '.session('source'));
return $dataTable->render('activities/index');
