HarmonyOS鸿蒙Next日历写入后，再次获取日历信息时，缺少identifier字段为undefined

开发者你好，这边本地设置日程、获取日程信息都是正常的，修改日程信息后也可以正常获取到identifier信息，为了进一步分析问题原因，方便的话可以提供下您这边的复现demo和设备的版本吗？

这边的本地demo如下，运行环境为6.0.0.107版本设备和6.0.0.858版本的DevEco Studio：

@Entry
@Component
struct Index {
  private atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
  private context = getContext() as common.UIAbilityContext;
  private permissions: Array<Permissions> = [
    'ohos.permission.READ_CALENDAR',
    'ohos.permission.WRITE_CALENDAR',
  ];
  private calendar: calendarManager.Calendar | undefined = undefined;
  // 指定日历账户信息
  private calendarAccount: calendarManager.CalendarAccount = {
    name: 'MyCalendar',
    type: calendarManager.CalendarType.LOCAL,
    // 日历账户显示名称，该字段如果不填，创建的日历账户在界面显示为空字符串。
    displayName: 'MyCalendar'
  };
  // 日历配置信息
  private config: calendarManager.CalendarConfig = {
    // 打开日程提醒
    enableReminder: true,
    // 设置日历账户颜色
    color: '#aabbcc'
  };
  private identifier_id: string = ''
  @State eventsInfo: string = '';
  @State eventIds: number[] = []

  aboutToAppear(): void {
    try {
      let calendarMgr = calendarManager.getCalendarManager(this.context);
      // 创建日历账户
      calendarMgr?.createCalendar(this.calendarAccount).then((data: calendarManager.Calendar) => {
        console.info(`Succeeded in creating calendar data->${JSON.stringify(data)}`);
        this.calendar = data;
        // 请确保日历账户创建成功后，再进行相关日程的管理
        // // 设置日历配置信息，打开日程提醒、设置日历账户颜色
        this.calendar.setConfig(this.config).then(() => {
          console.info(`Succeeded in setting config, data->${JSON.stringify(this.config)}`);
        }).catch((err: BusinessError) => {
          console.error(`Failed to set config. Code: ${err.code}, message: ${err.message}`);
        });
      }).catch((error: BusinessError) => {
        console.error(`Failed to create calendar. Code: ${error.code}, message: ${error.message}`);
      });
    } catch (e) {
    }
  }

  build() {
    Column() {
      Button('添加日程')
        .onClick(() => {
          const date = new Date();
          let event =
            this.createCourseReminderCalendarEvent('日程标识', '课程', date.getTime(), date.getTime() + 50 * 60 * 100,
              10, '本地日程')
          this.calendar?.addEvent(event, (err: BusinessError, data: number): void => {
            if (err) {
              console.error(`Failed to addEvent. Code: ${err.code}, message: ${err.message}`);
            } else {
              console.info(`Succeeded in adding event, id -> ${data}`);
              this.identifier_id = data.toString();
              this.eventIds.push(data);
            }
          });
        })
      Button('修改日程信息')
        .onClick(() => {
          const filter = calendarManager.EventFilter.filterById(this.eventIds);
          this.calendar?.getEvents(filter).then((data: calendarManager.Event[]) => {
            console.info(`Succeeded in getting events, data -> ${JSON.stringify(data)}`);
            let newEvent = data[0]
            newEvent.identifier = this.identifier_id
            this.calendar?.updateEvent(newEvent, (err: BusinessError) => {
              if (err) {
                console.error(`Failed to update event. Code: ${err.code}, message: ${err.message}`);
              } else {
                console.info("Succeeded in updating event");
              }
            });
          });
        })
      Button('查询当前日历下日程')
        .onClick(() => {
          // 根据MyEvent进行模糊查询，如果存在类似标题为MyEvent1类型的日程，也可查询出来
          const filter = calendarManager.EventFilter.filterByTitle('课程');
          this.calendar?.getEvents(filter, [
            'id', 'type', 'title',
            'location', 'startTime', 'endTime',
            'isAllDay', 'attendee', 'timeZone',
            'reminderTime', 'recurrenceRule', 'description',
            'service',
            'identifier',
            'isLunar',
          ], (err: BusinessError, data: calendarManager.Event[]) => {
            if (err) {
              console.error(`Failed to get events. Code: ${err.code}, message: ${err.message}`);
            } else {
              console.info(`Succeeded in getting events, data -> ${JSON.stringify(data)}`);
              this.eventsInfo = JSON.stringify(data)
            }
          });
        })
      Text(this.eventsInfo)
        .fontSize('15fp')
        .fontColor(Color.Black)
        .width('100%')
        .height('50%')
        .align(Alignment.Center)
    }
  }

在HarmonyOS Next中，日历写入后再次获取时缺少identifier字段为undefined，通常是因为权限配置问题或API调用时机不当。请检查是否已正确声明日历读写权限（ohos.permission.READ_CALENDAR和ohos.permission.WRITE_CALENDAR），并在获取数据前确保写入操作已完成。确认使用@ohos.calendar接口时，读取方法在写入回调成功后执行，避免异步操作导致数据未就绪。
