Symfony version(s) affected

6.4

Description

Unfortunately, the fix from #52422 did not help in the latest 6.4 version for me. Same Request and Project as before. Not 100% sure if this is a Serializer or MapRequestPayload Problem.

How to reproduce

Project updated to 6.4: https://github.com/Havrin/symfony-payload-bug

Sending a request against http://localhost/api/change-password with

{
  "password": "abc",
  "old_password": "def"
}

Results in:

object(App\DTO\ChangePassword)#192 (3) {
    [
        "oldPassword":"App\DTO\ChangePassword":private
    ]=>
  NULL
  [
        "email":"App\DTO\ChangePassword":private
    ]=>
  string(3) "abc"
  [
        "password":"App\DTO\ChangePassword":private
    ]=>
  string(3) "def"
}

Check var_dump in https://github.com/Havrin/symfony-payload-bug/blob/master/src/EventSubscriber/ExceptionResponseEventSubscriber.php

Btw. maybe the nullable oldPassword is a problem. Using a not nullable oldPassword can be tested by using the same payload against http://localhost/api/change-password-without-null

{
  "password": "abc",
  "old_password": "def"
}

Results in:

object(App\DTO\ChangePasswordWithoutNull)#192 (0) {
    [
        "email":"App\DTO\ChangePasswordWithoutNull":private
    ]=>
  uninitialized(string)
  [
        "password":"App\DTO\ChangePasswordWithoutNull":private
    ]=>
  uninitialized(string)
  [
        "oldPassword":"App\DTO\ChangePasswordWithoutNull":private
    ]=>
  uninitialized(string)
}

With all validations triggered (not only for the missing email). This is mentioned in #53075
