Hi, anyone seeing a weird bug after composer update today?

If my column in DB is a nullable string and set to null, Doctrine does not hydrate the property with null but “ignores” the property altogether, which results in
Typed property ... must not be accessed before initialization
Started happening today after composer update.

See element 0 of array - it is missing event property altogether.
It did not happen yesterday, yesterday it was hydrated normally null as you would expect.

The property is declared as Nullable? Weird only non nullable properties should use the class, maybe i am wrong and its all typed classes, then we need to check for allowsnull

Yes, it is declared as nullable, for reference:

/**
 * Fails
 * @ORM\Column(type="string", length=100, nullable=true)
 */
private ?string $event;

/**
* Works
* @ORM\Column(type="string", length=100, nullable=true)
*/
private $event;
