Symfony version(s) affected

7.3.0

Description

When using the ObjectMapper using Class-Level Transformation, I faced an issue related to the source instance.

According to the doc https://symfony.com/doc/current/object_mapper.html#class-level-transformation, the $source argument should be an instance of App/DTO/LegacyUserData but it is not the case. It is actually a App/Entity/User. Due to this, I always receive the following error :

Warning: Undefined property: App\Entity\User::$userId

How to reproduce

To reproduce the issue :

create a src/DTO/LegacyUserData.php DTO

create an entity class src/Entity/User.php

in a controller, we can do

using XDEBUG here is the result

Am I doing something wrong ?
