Symfony Doctrine ManyToMany关系:无法识别的领域

I came into a problem I can't solve for several days now.

I have a groupe table and a statistiquequestion table.

1 statistiquequestion --> several groupes 1 groupe --> several statistiquequestion

I set up a ManyToMany relationship.

Entities :

Groupe :

/**
 * Groupe
 *
 * @ORM\Table(name="groupe")
 * @ORM\Entity
 */
class Groupe
{
    ...
    /**
 * @ORM\ManyToMany(targetEntity="\PACES\StatistiqueBundle\Entity\StatistiqueQuestion", mappedBy="groupes",
 * cascade={"all"})
 */
private $statistiquesquestion;

....
}

StatistiqueQuestion :

/**
 * StatistiqueQuestion
 *
 * @ORM\Table(name="statistiquequestion")
 * @ORM\Entity
 */
class StatistiqueQuestion
{
   ...
   /**
 * @ORM\ManyToMany(targetEntity="\PACES\UserBundle\Entity\Groupe",inversedBy="statistiquesquestion" , cascade={"persist"})
 * @ORM\JoinColumn(name="groupe_id", referencedColumnName="id")
 */
private $groupes;

....
}

When I try to find a StatistiqueQuestion object, I have this error :

SQLSTATE[42S22]: Column not found: 1054 Unrecognized field 'statistiquequestion_groupe.groupe_id' in where clause

Here's my code to get the object :

                    $statsQuestion[]=$em->getRepository( StatistiqueQuestion::class )->findOneBy( [ 'question'  => $colle,
                                                                                             'groupes' => $groupes
                                                                                           ] );

When I dump $groupes, I get an array of objects as intended.
