Why does the File class error occur when uploading images?

Question

symfony

Files are uploaded via ajax in base64.
Saving a file:

if (strlen($this->request->request->get('avatar')) > 100) {
            $data = explode(',', $this->request->request->get('avatar'));
            $tmp['avatar'] = tmpfile();

            $path = stream_get_meta_data($tmp['avatar'])['uri'];
            file_put_contents($path, base64_decode($data[1]));

            $user->setAvatar(new File($path));
     }
//........
      if ($user->getAvatar()) {
                $name = $this->get('uploader')->moveFile($user->getAvatar(), 'user/a');
                $user->setAvatar($name);
      }
      $em->persist($user);

Now I keep getting the error

Serialization of 'Symfony\Component\HttpFoundation\File\File' is not allowed

.
What am I doing wrong?

Well, it’s humanly written to you that you can’t serialize an object of the File class. Look for where your serialization takes place.
