HarmonyOS鸿蒙Next中请求通知授权失败，错误码1600001

错误码1600001 内部错误

可能原因
多线程处理、内部处理异常等内核通用错误。

处理步骤
确认系统资源是否足够。
您这边先尝试下在应用加载如下demo页面看下是否存在问题，然后还存在问题，麻烦通过下最小复现demo，以便帮您分析问题。

```javascript
import notificationManager from '[@ohos](/user/ohos).notificationManager';

import { BusinessError } from '[@kit](/user/kit).BasicServicesKit';

import { common } from '[@kit](/user/kit).AbilityKit';

[@Entry](/user/Entry)
[@Component](/user/Component)
struct NotificationDemo { //文本通知

  onPageShow(): void {
    let context = getContext(this) as common.UIAbilityContext;

    notificationManager.requestEnableNotification(context).then(() => {
      console.info(`[initHuaweiPush]requestEnableNotification success`);
    }).catch((err: BusinessError) => {
      if (1600004 == err.code) {
        console.info(
          `[initHuaweiPush]requestEnableNotification refused, code is ${err.code}, message is ${err.message}`);
      } else {
        console.info(
          `[initHuaweiPush]requestEnableNotification failed, code is ${err.code}, message is ${err.message}`);
      }
    });
  }

  publishNotification_Text() {
    let notificationRequest: notificationManager.NotificationRequest = {
      id: 1,
      content: {
        notificationContentType: notificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT,
        // 普通文本类型通知
        normal: {
          title: '文本标题',
          text: '文本内容'
        }
      }
    };
    notificationManager.publish(notificationRequest)
  }

  build() {
    Column({ space: 20 }) {
      Button('发送普通文本通知')
        .onClick(() => { //确认通知授权
          // notificationManager.requestEnableNotification(); //发送文本通知
          this.publishNotification_Text()
        })
    }.width('100%').height('100%').justifyContent(FlexAlign.Center)
  }
