Edit Sonata User data - symfony

Question

I'm trying to override Sonata User Admin class, on my bundle. For the moment, I just override the configureListFields method:
namespace App\Admin;
use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\UserBundle\Admin\Model\UserAdmin as BaseUserAdmin;
class UserAdmin extends BaseUserAdmin
{
/**
* #param ListMapper $listMapper
*/
protected function configureListFields(ListMapper $listMapper):void
{
$listMapper
->addIdentifier('username')
->add('email')
->add('groups')
->add('enabled', null, ['editable' => true])
->add('accountType')
->add('createdAt')
;
if ($this->isGranted('ROLE_ALLOWED_TO_SWITCH')) {
$listMapper
->add('impersonating', 'string', ['template' => '#SonataUser/Admin/Field/impersonating.html.twig'])
;
}
}
}
I refresh my page and I got the list of users without problem. But when I click into a user to edit it, I have this error: Call to a member function getClass() on null on these lines:
$now = new \DateTime();
$genderOptions = [
'choices' => \call_user_func([$this->getUserManager()->getClass(), 'getGenderList']),
'required' => true,
'translation_domain' => $this->getTranslationDomain(),
];
// NEXT_MAJOR: Remove this when dropping support for SF 2.8
if (method_exists(FormTypeInterface::class, 'setDefaultOptions')) {
$genderOptions['choices_as_values'] = true;
}

If you want to access to your method getGenderList() from configureFormFields() you can do that :
protected function configureFormFields(FormMapper $formMapper)
{
$now = new \DateTime();
$genderOptions = [
'choices' => $this->getSubject()->getGenderList(), // here
'required' => true,
'translation_domain' => $this->getTranslationDomain(),
];
// NEXT_MAJOR: Remove this when dropping support for SF 2.8
if (method_exists(FormTypeInterface::class, 'setDefaultOptions')) {
$genderOptions['choices_as_values'] = true;
}
}
See the Symfony docs about it.
