PHP 8 Annotations bug?

Hello!

My stack:
php: 8.0.0
symfony: 5.2
doctrine/orm: 2.8.1
doctrine/doctrine-bundle: 2.2.2

I have the next entitity:

I try to request a user by his login through the repository
```php
return new Response(
$this->userRepository->findOneBy(['login' => 'someLogin'])->getLogin()
);
```

and catch the next error:

This is due to the fact that the Doctrine annotation parser tries to go through all the properties of the annotation @ORM\Id (see the first screenshot).
And since they don't exist, the foreach loop passes null and I catch this error.

To confirm my words, I attach screenshots from the xdebug:

Doctrine\Common\Annotations\CachedReader::getPropertyAnnotation()
