Symfony 3 — ожидаемый аргумент типа массив

Я нашел на все темы на Google и не получить решение.

У меня есть эта ошибка:

Ожидаемый аргумент типа «PL \ PlatformBundle \ Entity \ Module», «Doctrine \ Common \ Collections \ ArrayCollection»

Я хочу выбрать несколько модулей в списке, но когда я нажимаю «Сохранить», у меня появляется ошибка.

Моя форма:

use Doctrine\ORM\EntityRepository;

class AppAccueilModuleType extends AbstractType {
private $idCompany;

/**

public function buildForm(FormBuilderInterface $builder, array $options) {
$this->idCompany = $options['idCompany'];

$builder
->add('company', CollectionType::class, array(

},
