在将我的代码部署到云后使用google appengine时出现此错误,我使用objectify索引进行过滤.
这是我的包含索引的java类(Entity)文件
@Entity
public class Session{
@Index private Integer year;
@Index private Key<Institute> institute;
//some other manipulation goes below
}

当我尝试使用objectify从数据存储区调用实体列表时
ofy().load().type(Session.class).filter("institute",t).order("year").list();//order by year

它在我的控制台上抛出以下错误,下面的图像显示它,抱歉不太清楚
我有以下Enum类
public enum EventAccess {
PUBLIC("PUBLIC"),
EMPLOYEES_ONLY("EMPLOYEES_ONLY"),
String name;
private EventAccess(String name) {
this.name = name;
}
public String getName() {
return name;
}
}

此外,我有一个Serializable类,其枚举作为其中一个字段
public class EventAccessRequest implements Serializable{
private List<EventAccess> event_access = new ArrayList<>();
public EventAccessRequest() {
}
public List<EventAccess> getEvent_access() {
return event_access;
}
public void setEvent_access(List<EventAccess> event_access) {
this.event_access = event_access;
}

我有一个@Api方法,它创建了一个EventAccessRequest类型的对象.我在Api Explorer中设置了此请求的值,但它没有设置我放入的任何枚举字段.
@ApiMethod(name = "fetchEventByEventAccess", path = "user/events/list-by-access/", httpMethod = HttpMethod.GET)
public RestfulResponse fetchEventByEventAccess(EventAccessRequest request)throws Exception
{
EventAccess x = request.getEvent_access().get(0);
