多对多关系的查询构建器抛出 QueryException，为什么？

如何解决多对多关系的查询构建器抛出 QueryException，为什么？

我正在尝试选择存在 m-2-m 关系属性的所有实体。

$qb = $this->entityManager
    ->createqueryBuilder()
    ->select('attachment')
    ->from(Attachment::class,'attachment')
    ->join('attachment.orders','order');

 print $qb->getQuery()->getsql();
 // SELECT d0_.Meta AS Meta_0,d0_.type AS type_1,d0_.attachment_id AS attachment_id_2,d0_.dossier_id AS dossier_id_3 FROM dossier_attachment d0_ INNER JOIN dossier_order_attachment d2_ ON d0_.attachment_id = d2_.attachment_id INNER JOIN dossier_order d1_ ON d1_.order_id = d2_.order_id

这似乎纠正了我的多 2 多表的 sql。

但是，一旦我添加了一个 where 子句来限制返回的附件，我就会得到一个 QueryException。由于我已经玩了两个多小时，我在问为什么会出现异常以及我将如何解决它？
