New to symfony 5- Error "No route Found" for Form in PUT method

Question

i'm learning to use Symfony right now, and i'm having an issue with the routing system. I'm currently trying to edit a "Pin" using a form. So here is what I have in my controller so far for the update of a "Pin".

/**
 * @Route("/pins/{id<[0-9]+>}/edit", name="app_pins_edit", methods="GET|PUT")
 */
public function edit(Request $request, Pin $pin, EntityManagerInterface $em): Response
{

    
    $form = $this->createForm(PinType::class,$pin,[
        'method'=>'PUT'
    ]);

    $form->handleRequest($request);


    if ($form->isSubmitted() && $form->isValid()) {
        
        $em->flush();

        $this->addFlash('success','Pin successfully updated');

        return $this->redirectToRoute('app_home');
    }

    return $this->render('pins/edit.html.twig', [
        'pin' => $pin,
        'form' => $form->createView(),
    ]);
}

And the error I have is this one when I try to update a Pin : "No route found for "POST"Method Not Allowed (Allow: GET, PUT)".

I'm assuming it's because I wrote "methods="GET|PUT"" in my route. And this is what I actually need. But I keep having this error.

PS : With the createForm I have a hidden input in the form like this :

<input type="hidden" name="_method" value="PUT"

That is supposed to be read by symfony as "I want the put method" but doesn't seem to work.

Thank you for reading this ! And thank you for helping if you do!

PS : If you need more information or more code i'll be happy to share it with you.
