Symfony 4/JMS/FOSUser: Can't serialize datas from FOS\UserBundle

Question

There is A LOT of similar quesions, some of them have validated answers, but here I am and none of them worked.

My use case is pretty simple:

My users App\Client\common\Entities\User belong to a customer App\Client\common\Entities\Customer.
App\Client\common\Entities\User also inherits FOS\UserBundle\Model\User which contains the holy property "email"

I want to serialize all my customers AND their users (including their mail). Jms works pretty well except i can not access properties from the FOS\UserBundle\Model\User class.

following this answer here is what I have now.

jms_serializer.yml

jms_serializer:
    #blablablaa....
    metadata:
        auto_detection: true
        directories:
            App:
                namespace_prefix: 'App\Client'
                path: '%kernel.project_dir%/serializer'
            FOSUB:
                namespace_prefix: 'FOS\UserBundle'
                path: '%kernel.project_dir%/serializer'

serializer/App.Client.common.Entities.User.yml :

App\Client\common\Entities\User:
    exclusion_policy: ALL
    properties:
        surname:
            expose: true
            exclude: false
            groups: [export]

serializer/Model.User.yml:

FOS\UserBundle\Model\User:
    exclusion_policy: ALL
    properties:
        email:
            expose: true
            exclude: false
            groups: [export]

src/Command/DeploySyncUsersCommand.php:

protected function execute(InputInterface $input, OutputInterface $output)
{
    $users = $this->customerRepository->findAll(); //this is an array of Customer
    $context = new SerializationContext();
    $context->setGroups(['export']);
    $serializer = SerializerBuilder::create()->build();
    $json = $serializer->serialize($users, 'json', $context);
    // do something with json
}

Everything works fine except the json does NOT contain email or any FOSUser\User data.

Also something interesting is that I can write anything (even invalid yml) in the App.Client.common.Entities.User.yml and Model.User.yml files, I'm able to clear the cache with no errors. I have errors when I write invalid yml in jms_serializer.yml

Ok I've been able to solve this using dependency injection instead of building the serializer

/**
 * @var SerializerInterface
 */
private SerializerInterface $serializer;

/**
 * @var string
 */
private string $reportAnalysisUrl;

public function __construct(SerializerInterface $serialzer, $reportAnalysis)
{
    $this->serializer = $serialzer;
    parent::__construct();
}

protected function execute(InputInterface $input, OutputInterface $output)
{
    $users = $this->customerRepository->findAll();
    $context = new SerializationContext();
    $context->setGroups(['export']);
    $json = $this->serializer->serialize($users, 'json', $context);
    //do something with json
}

so now my yml files aren't ignored anymore
