Symfony Error when loading a Profile Form - symfony-forms

Question

I'm currently getting this error when trying to load an edit form for my Profile entity.
The form's view data is expected to be an instance of class AppBundle\Entity\Profile, but is a(n) array. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) array to an instance of AppBundle\Entity\Profile.
I was Wondering if anyone knows how to fit this. I'm using a Profile controller and the User and Profile have a OneToOne relationship with each other.
Here is my code for the Profile controller that loads that form
/**
* #Route("/profile/edit", name="profile_edit")
*/
public function editAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$profileRepository = $em->getRepository(Profile::class);
$user = $this->getUser();
$profile = $profileRepository->getProfileByUserId($user->getId());
$form = $this->createForm(ProfileType::class, $profile);
$form->handlerequest($request);
if( $form_.isSubmitted() && $form->isValid()) {
$firstname = $form->get('firstname')->getData();
$lastname = $form->get('lastname')->getData();
$description = $form->get('description')->getData();
$profile->setFirstname($firstname);
$profile->setLastName($lastname);
$profile->setDescription($description);
$em->persist($profile);
$em->flush();
$this->addFlash('flash-profileeditted', 'You\'ve successfully updated your profile.');
$this->redirectToRoute('profile_page');
}
return $this->render('profile/edit.html.twig', ['form' => createForm(), 'profile' => $profile]);
}
And here is my ProfileType::class
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('firstname', TextType::class, [ 'label' => 'Firstname', 'attr' => ['class' => 'form-control']])
->add('lastname', TextType::class, ['label' => 'Lastname', 'attr' => ['class' => 'form-control']])
->add('description', TextareaType::class, ['label' => 'In Your Own Words', 'attr' => ['class' => 'form-control']])
->add('user')
->add('submit', SubmitType::class, ['label' => 'Edit Profile', 'attr' => ['class' => 'btn btn-info']]);
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Profile'
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'appbundle_profile';
}
Not Sure what else to include here, hopefully everything is ok and the solution can be found within this code.
I should also point out that I am using FOSUserBundle.
Thanks in advance,

Ok. I finally found out what was happening. I was using the Profile Repository to find a user by their id, but that was returning an array. So what I had to do is use this code:
$profile = $profileRepository->findOneByUser($user->getId());
This actually returns the Object as an AppBundle\Entity\Profile object which can then be used to populate the form.
