Расширение дерева gedmo/dectrine не может использовать объект в качестве массива ⇐ Php

[Anonymous]

Я создал сущность с таблицей закрытия и хранилищем вместе. Я пробую базовый пример создания дерева, но вижу, как ошибка не может использовать объект приложения типа \ Entity \ Discurvess \ Comment As Array при вызове GetCommentTreeFordIscussion
entity:
#[Gedmo\Tree(type: 'closure')]
#[Gedmo\TreeClosure(class: CommentClosure::class)]
#[ORM\Entity(repositoryClass: CommentRepository::class)]

{
use IdentifiableEntity;
use TimestampableEntity;

#[ORM\Column(type: 'text')]
private string $content;

#[ORM\ManyToOne(targetEntity: User::class)]
