HarmonyOS 鸿蒙Next 长时任务（location任务类型失败，返回9800005）？

日志上看The bgMode is invalid，应该是长时任务的类型配置错误。
model.json5中做如下添加：

"backgroundModes": [
// 长时任务类型的配置项
  "location"
] 

开启定位长时任务和关闭长时任务的接口：

startLocationContinuousTask(){
  let wantAgentInfo: wantAgent.WantAgentInfo = {
    // 点击通知后，将要执行的动作列表
    wants: [
      {
        bundleName: "com.example.backgroundtask",
        abilityName: "EntryAbility"
      }
    ],
    // 点击通知后，动作类型
    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]
  };
try {
//通过wantAgent模块下getWantAgent方法获取WantAgent对象
wantAgent.getWantAgent(wantAgentInfo).then((wantAgentObj: WantAgent) => {
try {
backgroundTaskManager.startBackgroundRunning(getContext(this) as common.UIAbilityContext,
backgroundTaskManager.BackgroundMode.LOCATION, wantAgentObj).then(() => {
console.info(“Operation startBackgroundRunning succeeded”);
    }).catch((error: BusinessError.BusinessError) => {
      console.error(`Operation startBackgroundRunning failed. code is ${error.code} message is ${error.message}`);
    });
  } <span class="hljs-keyword">catch</span> (error) {
    console.error(` startBackgroundRunning failed. code is ${(error as BusinessError.BusinessError).code} message is ${(error as BusinessError.BusinessError).message}`);
  }
});
} catch (error) {
console.error(Operation getWantAgent failed. code is ${(error as BusinessError.BusinessError).code} message is ${(error as BusinessError.BusinessError).message});
}
}
//关闭长时任务
stopLocationContinuousTask() {
backgroundTaskManager.stopBackgroundRunning(getContext(this) as common.UIAbilityContext).then(() => {
console.info(Succeeded <span class="hljs-keyword">in</span> operationing stopBackgroundRunning.);
}).catch((error: BusinessError.BusinessError) => {
console.error(Failed to operation stopBackgroundRunning. Code is ${error.code}, message is ${error.message});
});
}
