Modifier une image avec VichUploader

Bonjour à tous,

Voilà, dans mon projet Symfony, je cherche à modifier l'image d'une tente sur ma route edit.
Pour info, la tente à son entité (Tent) et les images ont leur entité aussi (Image).

Merci pour votre aide.

TentController.php

#[Route('/edit/{tent}', name: 'edit', methods: ['GET', 'POST'])]
    public function edit(Request $request, Tent $tent, TentRepository $tentRepository): Response
    {
        $form = $this->createForm(TentType::class, $tent);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $existingImages = $tent->getImage();
            dump('existingImages', $existingImages);

            foreach ($existingImages as $existingImage) {
                dump('existingImage', $existingImage);

                if ($form->has('imageFile')) {
                    $imageFile = $form->get('imageFile')->getData();
                    dump('imageFile', $imageFile);

                    $existingImage->setImageFile($imageFile);
                }
            }

            $tentRepository->save($tent, true);
            $this->addFlash('success', 'La categorie {$tent->getName()} a bien été modifiée');

            return $this->redirectToRoute('admin_tent_index', [], Response::HTTP_SEE_OTHER);
        }

        return $this->renderForm('admin/tent/edit.html.twig', [
            'tent' => $tent,
            'form' => $form,
        ]);
    }
