Wso2 msf4j请求在http连接器侦听器中出现异常错误

我使用msf4j框架创建了一个微服务，使用Hibernate jpa配置了postgres数据库，并启动了服务器

我可以成功地执行post/get操作，但在后端会出现以下错误。谁能指导我解决这个问题

Hibernate: 
    select
        user0_.id as id1_0_0_,
        user0_.firstName as firstNam2_0_0_,
        user0_.lastName as lastName3_0_0_ 
    from
        USER_DETAIL user0_ 
    where
        user0_.id=?
