BC Break	no
Version	2.18.0

Summary

When you have a cached entity that references a non cached entity, you'll get an exception.

Current behavior

Trying to call any find method on the entity repository of the cached entity will result in:

In DefaultQueryCache.php line 340:
                                                                                                                                
  Attempted to call an undefined method named "getCacheRegion" of class "Doctrine\ORM\Persisters\Entity\BasicEntityPersister".  

How to reproduce

#[Entity(repositoryClass: FooRepository::class)]
#[Cache(usage: 'NONSTRICT_READ_WRITE', region: 'write_rare')]
class Foo {
    #[Id]
    #[Column(type: UuidType::NAME)]
    private Uuid $id;

    #[OneToOne(mappedBy: 'foo', targetEntity: Bar::class, fetch: 'EXTRA_LAZY')]
    private ?Bar $bar = null;
}

#[Entity(repositoryClass: BarRepository::class)]
class Bar {
    #[Id]
    #[Column(type: UuidType::NAME)]
    private Uuid $id;

    #[OneToOne(inversedBy: 'bar', targetEntity: Foo::class)]
    #[JoinColumn(nullable: false, onDelete: 'CASCADE')]
    private Foo $foo;
}

Now call for example findAll() on FooRepository

Expected behavior

No exception
