Java 执行计数语句时JPA和Hibernate库出现问题

在前一周左右的时间里，我一直在徒劳地努力工作

我可以执行简单的查询，例如按id查找实体，或获取实体集合等，但是，当我尝试执行更复杂的查询时，我似乎总是遇到错误。是否有人可以帮助调试此COUNT语句，该语句会产生以下错误堆栈跟踪：

Caused by: org.hibernate.query.sqm.InterpretationException: Error interpreting query [SELECT COUNT(a.id) FROM AgreementEntity a]; this may indicate a semantic (user query) problem or a bug in the parser
Caused by: java.lang.NullPointerException

以下是导致错误的代码：

    EntityManager em = getFirstEntityManager();
    Session session = em.unwrap(Session.class);
    // The following line of code causes an error
    session.createQuery("SELECT COUNT(a.id) FROM AgreementEntity a");

下面是整个
