我不明白为什么我的jpql表达式是错误的。我想得到没有从我的数据库中删除的自行车列表，目前正在租赁。你能帮助我吗？

@Data
@MappedSuperclass
public abstract class AbstractEntity implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Basic(optional = false)
    @Column(nullable = false)
    private boolean isRemoved;
}

@Data
@Entity
@NamedQueries({
        @NamedQuery(name = "Bike.findRent", query = "SELECT b FROM Bike b WHERE NOT b.isRemoved AND b.isRent")
})
public class Bike extends AbstractEntity {

    @Basic(optional = false)
    @Column(nullable = false)
    private boolean isRent;
}

@Repository
public class BikeDao extends BaseDao<Bike> {

    public BikeDao() {
        super(Bike.class);
    }

    public List<Bike> findRent() {
        return em.createNamedQuery("Bike.findRent", Bike.class).getResultList();
    }
}

在我运行我的spring应用程序并通过postman尝试发布自行车数据之后。但是，

Caused by: org.eclipse.persistence.exceptions.EntityManagerSetupException: 
Exception Description: Deployment of PersistenceUnit [default] failed. Close all factories for this PersistenceUnit.
Internal Exception: Exception [EclipseLink-0] (Eclipse Persistence Services - 2.7.7.v20200504-69f2c2b80d): org.eclipse.persistence.exceptions.JPQLException
Exception Description: Syntax error parsing [SELECT b FROM Bike b WHERE NOT b.isRemoved AND b.isRent].

这是什么意思？我查不出哪里出了问题。
