Java Hibernate HQL返回多个值时在解析时引发NullPointerException

我对HQL查询有问题。我希望在一个查询中返回多个值（基本上是一个包含实体和布尔值的元组，无论该实体是否存在某些内容）

我在SpringDataJPA中使用JPA存储库

我的问题是：

@Query("select os, exists("
        + " select z from Zaznam z"
        + " inner join z.instanciaOkna io with (io.okno = :okno)"           
        + " where z.osoba = os)"
        + " from Osoba os where os in (:osoby)")
public List<Object[]> findPritomneOsoby(@Param("osoby") List<Osoba> osoby, @Param("okno") Okno okno);
