HarmonyOS鸿蒙Next中做一个计时工具设置代理提醒时候出现问题

const TAG: string = '[Page2]';
const DOMAIN_NUMBER: number = 0xFF00;
const REMINDER_ID: number = 100;

@Component
struct Page2 {
  @State message: string = 'Reminder Controller';
  private context: common.UIAbilityContext = this.getContext(this) as common.UIAbilityContext;
  private reminderId: number = REMINDER_ID;

  // 提醒代理配置
  private targetReminderAgent: reminderAgentManager.ReminderRequestTimer = {
    reminderType: reminderAgentManager.ReminderType.REMINDER_TYPE_TIMER,
    triggerTimeInSeconds: 10,
    actionButton: [
      {
        title: '关闭',
        type: reminderAgentManager.ActionButtonType.ACTION_BUTTON_TYPE_CLOSE
      }
    ],
    wantAgent: {
      pkgName: 'com.example.myapplication',
      abilityName: 'EntryAbility'
    },
    title: '定时提醒',
    content: '您设置的10秒倒计时已到！',
    expiredContent: '提醒已过期',
    notificationId: REMINDER_ID,
    slotType: notificationManager.SlotType.SOCIAL_COMMUNICATION
  };

  // 生命周期函数：组件创建时自动检查权限
  aboutToAppear() {
    this.checkAndRequestNotificationPermission();
  }

  // 检查通知权限
  private async checkAndRequestNotificationPermission() {
    try {
      const isEnabled = await notificationManager.isNotificationEnabled();
      hilog.info(DOMAIN_NUMBER, TAG, `通知权限状态: ${isEnabled}`);
      if (!isEnabled) {
        await notificationManager.requestEnableNotification(this.context);
        hilog.info(DOMAIN_NUMBER, TAG, '已请求通知权限');
      }
    } catch (err) {
      hilog.error(DOMAIN_NUMBER, TAG, `权限检查失败: ${err.code} - ${err.message}`);
    }
  }

  // 发布提醒
  private async publishReminder() {
    try {
      this.reminderId = await reminderAgentManager.publishReminder(this.targetReminderAgent);
      hilog.info(DOMAIN_NUMBER, TAG, `提醒发布成功，ID: ${this.reminderId}`);
      this.message = '提醒已设置（10秒）';
    } catch (err) {
      hilog.error(DOMAIN_NUMBER, TAG, `发布失败: ${err.code} - ${err.message}`);
      this.message = '设置提醒失败';
    }
  }

  // 取消提醒
  private async cancelReminder() {
    try {
      await reminderAgentManager.cancelReminder(this.reminderId);
      hilog.info(DOMAIN_NUMBER, TAG, '提醒已取消');
      this.message = '提醒已取消';
    } catch (err) {
      hilog.error(DOMAIN_NUMBER, TAG, `取消失败: ${err.code} - ${err.message}`);
      this.message = '取消提醒失败';
    }
  }

  build() {
    Column() {
      Text(this.message)
        .fontSize(20)
        .margin(20)

      Button('设置10秒提醒')
        .width(200)
        .height(60)
        .margin(10)
        .onClick(() => {
          this.publishReminder();
        })

      Button('取消提醒')
        .width(200)
        .height(60)
        .margin(10)
        .onClick(() => {
          this.cancelReminder();
        })
    }
    .width('100%')
    .height('100%')
    .justifyContent(FlexAlign.Center)
  }
}

上面是我关于代理提醒的代码，当我允许通知后，点击设置10秒提醒的按钮报错：发布失败: 67108878 - Inner error.点击取消提醒按钮也报错：取消失败: 1700003 - BussinessError 1700003: The reminder not exist.为啥呢
