Обратите внимание, что хотя параметр `item` был объявлен таким же способом, как и раньше, теперь предполагается, что он находится внутри тела с ключом `item`.

Notez que, bien que `item` ait été déclaré de la même manière qu'auparavant, il est désormais attendu à l'intérieur du corps de la requête sous la clé `item`.
