Typed property App\CategoryContractor::$id must not be accessed before initialization

/**
 * @Cycle\Entity(table="category_contractor")
 */
class CategoryContractor
{
    /**
     * @Cycle\Column(type="primary")
     */
    public int $id;
}

Can you provide the ORM version, list of connected entities and full stack trace.

What i'm trying to do

foreach ($contractors as $contractor) {
    foreach ($categories as $category) {
            $contractor->getCategories()->add($category);
            $tr->persist($contractor);
        }
}

$tr->run();

As a temporal solution i removed type int from property $id

As a temporal solution i removed type int from property $id

Как временное решение можно также определять поле как ?int $id = null. В какой-то степени это даже логично.

[wolfy-j]

Если I’d генерируясь базой то он должен быть nullable. По другому ОРМ просто не знает где взять данные.

[adamdyson]

/**
 * @Column(type = "primary")
 */
protected ?int $id = null;
