How to deserialize json array with OneToMany relationship?

Question

symfony

Hello, I threw in a code of such a plan, at the output I get two Users objects, everything is as it should be, but without a nested ipContract object, the question is whether symfony can deserialize the josons array in such a way that an object with data is also created in the ipContract that is associated with the User by the OneToMany relationship

$normalizer = [
            new ObjectNormalizer(),
            new ArrayDenormalizer()
        ];

        $encoders = [
            'json' => new JsonEncoder()
        ];

        $serializer = new Serializer($normalizer, $encoders);
        $jsonUser = [
            [
                'lastName' => 'Алексей',
                'firstName' => 'Виноградов',
                'fullName' => 'Алексей Виноградов',
                ],
            [
                'lastName' => 'Полина',
                'firstName' => 'Котова',
                'fullName' => 'Полина Котова',
                'ipContract' => [
                        'number' => '1-10-25',
                        'ammount' => '3500'
                    ]
                ]
            ];
        $jsonUser = json_encode($jsonUser);
        $serializeDataUsers = $serializer->deserialize($jsonUser, 'App\Entity\User[]', 'json');

At the output I get an array of objects but without ipContract, although logically Polina Kotova should have them, I attach a screenshot of the output

Symfony serializer how to deserialize an array with objects?
Plus, you need to write the types in phpDoc

/**
 * @var \App\Entity\IpContract[]
 *
 * @ORM\OneToMany(targetEntity="App\Entity\IpContract", mappedBy="users", orphanRemoval=true)
 */
private $ipContracts;
