$query = $em->createQuery("
SELECT u.nomUtilisateur, u.prenomUtilisateur
FROM App\Entity\Pointage po
LEFT JOIN App\Entity\EtudiantCours ec ON po.utilisateurEtudiant = ec.etudiant
JOIN App\Entity\Utilisateur u ON po.utilisateurEtudiant = u.id

->setParameter('idCours', $idCours);
->setParameter('idDate', $idDate);
->setParameter('idCreneau', $idCreneau);
$products = $query->getResult();
return $products;
}

Answer 1

You are missing the ; semicolon symbol:
// before
->setParameter('idCours', $idCours)
->setParameter('idDate', $idDate)
->setParameter('idCreneau', $idCreneau)
// after
->setParameter('idCours', $idCours)
->setParameter('idDate', $idDate)
->setParameter('idCreneau', $idCreneau); // <---- HERE!
Also in DQL there's no ON when joining, should be WITH instead. Read the DQL's documentation how to query related entities properly.
