Получатель Symfony 2 возвращает ошибку: {& quot; __ инициализатор __ & quot;: {}, & quot; __ cloner __ & quot;: {}, & quot; __ isInitialized __ & quot;: false}

У меня проблема с геттером, созданным Symfony 2 при попытке создать JSON. Получатель — getNcomptador (), который возвращает вид ошибки.

Вызванная функция для создания JSON:

public function llistatLecturesAction($db){

$sessio = $this->getRequest()->getSession()->get('aquagest');

$arrayAuxiliar = array();

$lecturesRepository = $this->getDoctrine()
->getRepository('AquagestLecturesBundle:Lectura', 'aquagest_'.$db);
$lectures = $lecturesRepository->findBy(array(),array('id'=>'ASC'));

$elmarray = array();

foreach ($lectures as $lectura) {
$aux['id'] = $lectura->getId();
$aux['any'] = $lectura->getLecany();
$aux['trimestre'] = $lectura->getTrimestre();
$aux['lectura'] = $lectura->getLectura();
$aux['nComptador'] = $lectura->getNcomptador();
//if($lectura->getId() == 1) $prova = $lectura->getNcomptador();

array_push($elmarray, $aux);
$i++;
}

return new JsonResponse($elmarray);

}
