Put request entity linked to some others entity symfony - rest

Question

i'm stucked on something: i have to entity Profile and Job
in the Job entity i have :
/**
* #var string
* #Gedmo\Translatable
* #ORM\Column(name="label", type="string", length=255)
* #Serializer\Groups({"profile_details","profile_put"})
* #Serializer\Type("string")
* #Serializer\Expose()
*/
private $label;
in the Profile entity i have :
* #var Job
*
* #Assert\NotBlank(message="app.profile.job.not_blank")
* #ORM\ManyToOne(targetEntity="App\Entity\Job")
* #ORM\JoinColumn(name="job_id", referencedColumnName="id")
* #Serializer\Groups({"profile_details","user_details","corporate_details","profile_put"})
* #Serializer\Type("App\Entity\Job")
* #Serializer\Expose()
*/
private $job;
/**
* #return Job
*/
public function getJob(): Job
{
return $this->job;
}
/**
* #param Job $job
*
* #return Profile
*/
public function setJob(Job $job): Profile
{
$this->job = $job;
return $this;
}
EDIT:
in the controller :
public function putAction(Request $request, Profile $profile): Profile
{
$profile
->setJob($request->get('job'))
$errors = $this->validator->validate($profile);
if (count($errors) > 0) {
throw new UnprocessableEntityHttpException((string) $errors);
}
$this->entityManager->persist($profile);
$this->entityManager->flush();
return $profile;
}
I'm trying to perform a put on the Profile entity to change some normal string fields. I don't know how to set the put request body on postman, i tried to put just the label but i got : "Argument 1 passed to App\\Entity\\Profile::setJob() must be an instance of App\\Entity\\Job, array given, called in /srv/api/src/Controller/ProfileController.php on line 114"
