#[ApiResource] attribute causing exception in OneToMay resource - symfony

Question

I have two related doctrine entities:
Content
#[ApiResource(operations: [new Get(), new Patch(), new Delete(), new Put(), new Post(uriTemplate: '/contents/add_text', controller: ContentTextPersist::class, read: false, openapiContext: ['description' => 'This endpoint provides a way to add content text and variants to a content object without incurring circular reference issue as a result of the nested nature of the Content -> ContentText and ContentTextVariants.', 'summary' => 'Persist new content text item and it\'s translations.']), new Post(), new GetCollection()], order: ['createdAt' => 'DESC'], normalizationContext: ['groups' => ['content:read']], denormalizationContext: ['groups' => ['content:write']], filters: ['translation.groups'])]
#[ORM\Entity]
#[ORM\HasLifecycleCallbacks]
class Content extends AbstractTranslatable
{
....
/**
* #var \Doctrine\Common\Collections\Collection<int, \App\Entity\ContentText>|\App\Entity\ContentText[]
*/
#[ORM\OneToMany(targetEntity: ContentText::class, mappedBy: 'content', orphanRemoval: true, cascade: ['persist'])]
#[Groups(['content:read', 'content:write'])]
private iterable $text;
...
public function __construct()
{
parent::__construct();
$this->text = new ArrayCollection();
}
...
/**
* #return Collection|ContentText[]
*/
public function getText() : Collection
{
return $this->text;
}
public function addText(ContentText $text) : self
{
if (!$this->text->contains($text)) {
$this->text[] = $text;
$text->setContent($this);
}
return $this;
}
public function removeText(ContentText $text) : self
{
if ($this->text->removeElement($text)) {
// set the owning side to null (unless already changed)
if ($text->getContent() === $this) {
$text->setContent(null);
}
}
return $this;
}
}
ContentText
#[ApiResource(operations: [new Patch(), new Delete(), new Get(), new GetCollection()], order: ['createdAt' => 'DESC'], paginationPartial: true, normalizationContext: ['groups' => ['contentText:read']], denormalizationContext: ['groups' => ['contentText:write']], filters: ['translation.groups'])]
#[ORM\Entity]
#[ORM\HasLifecycleCallbacks]
class ContentText
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column(type: \Doctrine\DBAL\Types\Types::INTEGER)]
#[Groups(['contentText:read', 'content:read'])]
private ?int $id = null;
public function getId() : ?int
{
return $this->id;
}
}
Would anyone know why if I remove #[ApiResource] attribute from ContentText entity then I'm able to get the collection of ContentText related to Content otherwise I get the error below:
"Unable to generate an IRI for the item of type \"App\\Entity\\ContentText\""
