doctrine getRepository errors - symfony

Question

I have problem with authentication via jwt:
public function getUser($credentials, UserProviderInterface $userProvider)
{
try {
$credentials = str_replace('Bearer ', '', $credentials);
$jwt = (array) JWT::decode(
$credentials,
$this->params->get('jwt_secret'),
['HS256']
);
return $this->em->getRepository(User::class)
->findOneBy([
'username' => $jwt['user'],
]);
}catch (\Exception $exception) {
throw new AuthenticationException($exception->getMessage());
}
}
I have this function and while entering valid credentials im getting this error: „Credentials check failed as the callable passed to CustomCredentials did not return \u0022true\u0022.”
I thought maybe in return function getRepository wants my repository of user entity, I passed parameters: getRepository(UserRepository::class) but im getting different error: The class \u0027App\UserRepository\u0027 was not found in chain configured namespaces App\Entity
And right now im kinda stuck without any good ideas and i would be grateful for and ides/thoguhts/clues
Edit1.
I thought that maybe in getRepository() parameter should be passed as string but also no, im getting error of: Class \u0027User\u0027 does not exist
Edit2.
UserRepository.php:
<?php
namespace App\Repository;
use App\Entity\User;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;
use Symfony\Component\Security\Core\Exception\UnsupportedUserException;

use Symfony\Component\Security\Core\User\PasswordUpgraderInterface;

class UserRepository extends ServiceEntityRepository implements PasswordUpgraderInterface
{
public function __construct(ManagerRegistry $registry)
{
parent::__construct($registry, User::class);
}
public function upgradePassword(PasswordAuthenticatedUserInterface $user, string $newHashedPassword): void
{
if (!$user instanceof User) {
throw new UnsupportedUserException(sprintf('Instances of "%s" are not supported.', \get_class($user)));
}
$user->setPassword($newHashedPassword);
$this->_em->persist($user);
$this->_em->flush();
}
// /**

You are missing a link to your Repository class.
Edit your #ORM\Entity annotation with:
use App\Repository\UserRepository;
/**
* #ApiResource()
* #ORM\Entity(repositoryClass=UserRepository::class)
* #UniqueEntity(fields="email", message="Email already taken")
* #UniqueEntity(fields="username", message="Username already taken")
*/
#[ApiResource]
class User implements UserInterface
{
