Nelmio API doc bundle post request with boolean always returns true - rest

Question

I'm developping a Symfony 4 API REST app with Nelmio Api Doc Bundle v3.
I am sending this request :
curl -X POST "http://dev.api_events.jessie/api/event-types" -H "accept: application/json" -H "Authorization: Bearer ZmU1MTgxNzNkZjM5ZTU2NzdiODVkODgxMmE2ZmE2OWUyMjY1ZWIxYzgxMjdlOTA3NjBiODM5Yzg1NTEzNjFlYw" -H "Content-Type: application/x-www-form-urlencoded" -d "fullName=aaaaaaaaaaa&shortName=aaaaaaaaaaa&dns=aaaaaaaaaa**&mandatoryRegistration=false"**
This is the response body :
{
"id": 19,
"full_name": "aaaaaaaaaaa",
"short_name": "aaaaaaaaaaa",
"dns": "aaaaaaaaaa",
**"mandatory_registration": true,**
"places": [],
"participation_types": []
}
I have absolutely no idea why i send mandatoryRegistration=false and my response have "mandatory_registration": true.
I paste my Controller, Form, Entity code below. And the nelmio api doc and fos_rest configuration code.
Controller :
/**
* Creates a new eventType entity.
*
* #Route("/event-types", methods="POST")
* #Operation(
* tags={"event_type"},
* summary="Creates a new event type entity",

public function postEventTypeAction(Request $request, EntityManagerInterface $em)
{
$event_type = new EventType();
$form = $this->createForm(EventTypeType::class, $event_type);
$form->submit($request->request->all()); // Validation des données
if ($form->isValid()) {
$em->persist($event_type);
$em->flush();
return View::create($event_type, Response::HTTP_CREATED , []);
}
else{
return View::create($form, Response::HTTP_BAD_REQUEST , []);
}
}
EventType form :

{
$resolver->setDefaults(array(
'data_class' => EventType::class
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'event_type';
}
}
EventType entity :
class EventType
{
/**

Answer 1

I tried some debug and find out i was trying to put a string in a boolean field which always returns true ...
Here's my solution : do not send "false" in the request, instead send 0 or 1 :
Controller edit :
/* #SWG\Parameter(
* name="mandatoryRegistration",
* in="formData",
* description="is the registration mandatory?",
* required=true,
* type="integer",
* enum={0,1}
* ),
