【求助】前台Service无法发布通知

https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ability-service-foreground-0000000000044473

按照官方文档创建前台Service，

权限也声明了

在Service的onStart中加入如下代码，但是按照文档中的写法根本无法发布通知

除非取消注释才能接收到，请问如何解决

NotificationRequest request = new NotificationRequest(1005);
        NotificationRequest.NotificationNormalContent content = new NotificationRequest.NotificationNormalContent();
        content.setTitle("title").setText("text");
        NotificationRequest.NotificationContent notificationContent = new NotificationRequest.NotificationContent(content);
        request.setContent(notificationContent);
//        try {
//            NotificationHelper.publishNotification(request);
//        } catch (RemoteException e) {
//            e.printStackTrace();
//        }

        // 绑定通知，1005为创建通知时传入的notificationId
        keepBackgroundRunning(1005, request);
