Erro envolvendo Construct e o AlunoRepository

Estava seguindo os passos do instrutor e acabei dando de cara com um erro informando que argumentos do construct não foram enviador

PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function Doctrine\ORM\EntityRepository::__construct(), 0 passed in /home/ramos/PhpstormProjects/Estudos/estudoDoctrine/commands/relatorio-aluno-repository.php on line 14 and exactly 2 expected in /home/ramos/PhpstormProjects/Estudos/estudoDoctrine/vendor/doctrine/orm/lib/Doctrine/ORM/EntityRepository.php:72

AlunoRepository:

<?php


namespace Ramos\estudoDoctrine\Repository;


use Doctrine\ORM\EntityRepository;
use Ramos\estudoDoctrine\Entity\Aluno;

class AlunoRepository extends EntityRepository
{
    public function buscaCursosPorAluno()
    {
        $entityManager = $this->getEntityManager();
        $classeAluno = Aluno::class;
        $dql = "SELECT aluno, telefones, cursos FROM $classeAluno aluno JOIN aluno.telefones telefones JOIN aluno.cursos cursos";
        $query = $entityManager->createQuery($dql);

        return $query->getResult();
    }
}

Arquivo de teste:

<?php

use Doctrine\Common\Collections\Collection;
use Doctrine\DBAL\Logging\DebugStack;
use Ramos\estudoDoctrine\Entity\Aluno;
use Ramos\estudoDoctrine\Entity\Telefone;
use Ramos\estudoDoctrine\Helper\EntityManagerFactory;
use Ramos\estudoDoctrine\Repository\AlunoRepository;

require_once __DIR__ . '/../vendor/autoload.php';

$debugStack = new DebugStack();
$entityManagerFactory = new EntityManagerFactory();
$repository = new AlunoRepository();

$entityManager = $entityManagerFactory->getEntityManager();
$entityManager->getConfiguration()->setSQLLogger($debugStack);

/*
 *@var Aluno[] $alunos
 */
$alunos = $repository->buscaCursosPorAluno();

foreach ($alunos as $aluno){

    $telefones = $aluno->getTelefones() ->map(function (Telefone $telefone){
        return $telefone->getNumero();
    }) -> toArray();

    /**
     * @return Collection
     */
    $cursos = $aluno->getCurso();

    echo "ID: {$aluno->getId()}\n";
    echo "Nome: {$aluno->getNome()}\n";
    echo "Telefones:" . implode(",", $telefones) . " \n";

    foreach ($cursos as $curso){
        echo "\tID: {$curso->getId()}\n";
        echo "\tNome: {$curso->getNome()}\n";
        echo "\t \n";
    }

}

print_r($debugStack);
