use AppBundle\FriendsSuggestions\RecommenderService;

class FriendsController extends AbstractController
{
    /**
     * @Route("/friends", name="app.friends.index", methods={"GET", "HEAD"})
     */
    public function index(UsersRepositoryInterface $users, Client $neo4jclient) : Response
    {
        $user = $this->getUser();
        $suggestedUsers = [];

        try {
            $recommender = new RecommenderService($neo4jclient);
            $recommendation = $recommender->recommendFriendsForuser($user);

It seems like $user can also be of type null; however, parameter $user of AppBundle\FriendsSuggestions\RecommenderService::recommendFriendsForuser() does only seem to accept Angelov\Donut\Users\User, maybe add an additional type check?

            foreach ($recommendation->getItems() as $item) {
                $suggestedUsers[] = $users->find($item->item()->value('id'));
            }
        } catch (\Exception $e) {

Consider adding a comment why this CATCH block is empty.

        }

        return $this->render('friends/index.html.twig', [
            'suggested_users' => $suggestedUsers
        ]);
    }
