HarmonyOS Next中长时任务报错有遇到的大佬吗？

Question

按照官方文档开启长时任务：

startContinuousTask() { 
  let wantAgentInfo: wantAgent.WantAgentInfo = { 
    // 点击通知后，将要执行的动作列表 
    // 添加需要被拉起应用的bundleName和abilityName 
    wants: [ 
      { 
        bundleName: "com.xxxx.xxxx.news", 
        abilityName: "com.xxxx.xxxx.news.EntryAbility" 
      } 
    ], 
    // 指定点击通知栏消息后的动作是拉起ability 
    actionType: wantAgent.OperationType.START_ABILITY, 
    // 使用者自定义的一个私有值 
    requestCode: 0, 
    // 点击通知后，动作执行属性 
    wantAgentFlags: [wantAgent.WantAgentFlags.UPDATE_PRESENT_FLAG] 
  }; 
 
  // 通过wantAgent模块下getWantAgent方法获取WantAgent对象 
  wantAgent.getWantAgent(wantAgentInfo).then((wantAgentObj: WantAgent) => { 
    backgroundTaskManager.startBackgroundRunning(getContext(), 
      backgroundTaskManager.BackgroundMode.AUDIO_RECORDING, wantAgentObj).then(() => { 
      console.info(`Succeeded in operationing startBackgroundRunning.`); 
    }).catch((err: BusinessError) => { 
      console.error(`Failed to operation startBackgroundRunning. Code is ${err.code}, message is ${err.message}`); 
    }); 
  }); 
} 
 
 
stopContinuousTask() { 
  backgroundTaskManager.stopBackgroundRunning(getContext()).then(() => { 
    console.info(`Succeeded in operationing stopBackgroundRunning.`); 
  }).catch((err: BusinessError) => { 
    console.error(`Failed to operation stopBackgroundRunning. Code is ${err.code}, message is ${err.message}`); 
  }); 
}

调用stopContinuousTask方法报错：
Failed to operation stopBackgroundRunning. Code is 9800005, message is BussinessError 9800005: Continuous Task verification failed. The application has not applied for a continuous task.

长时任务有约束和限制，其中运行限制里面，如果应用申请了长时任务，但是未真正执行申请类型的长时任务或申请类型的任务已结束，系统会对应用进行管控。
简单的说，申请完长时任务，系统会在5秒之内检测是都执行申请类型的长时任务，没有，就直接结束任务了，那再触发stopContinuousTask就会报这个错。
约束限制可参见指导：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides...约束与限制
