HarmonyOS鸿蒙Next中request.uploadFile获取不到返回值，上传没效果（可有偿）

上传文件，不知道上次成功还是失败，没有接口返回值找不到问题所在。大佬指教下，真没招了。
可以加联系方式V，可有偿：Rik-Q1129
代码稍微改动了下。使用的是api13

现在“uploadTask参数”打印出来是空对象，走的catch。

import { common } from "@kit.AbilityKit";
import fs from '@ohos.file.fs';
import { BusinessError, request } from "@kit.BasicServicesKit";
import { photoAccessHelper } from "@kit.MediaLibraryKit";
// 获取应用文件路径
let context = getContext(this) as common.UIAbilityContext;
let cacheDir = context.cacheDir;

/**
 * 从相册中获取文件
 */
export async function PickerPhoto(){
  // const options = new picker.PhotoSelectOptions() //api-12已弃用
  const options = new photoAccessHelper.PhotoSelectOptions
  //最多选择一个
  options.maxSelectNumber = 1;
  //文件类型
  options.MIMEType = photoAccessHelper.PhotoViewMIMETypes.IMAGE_TYPE
  //获取选中的图片地址
  const optionsView = new photoAccessHelper.PhotoViewPicker()
  let urls = await optionsView.select(options)

  // 没有选择的情况
  if(urls.photoUris.length<=0)return;
  let imgUrl = urls.photoUris[0]
  return imgUrl
}

/**
 * 将本地图片  文件拷贝到cache缓存目录
 */
export function copyImgToCache(photoImgPath:string){
  const file = fs.openSync(photoImgPath,fs.OpenMode.READ_ONLY)
  // 文件唯一标识
  let fileFD = file.fd
  let fileName = Date.now().toString() //避免文件重复，重新文件名
  const ext = 'jpg'
  let fullPath = cacheDir + "/" + fileName + "." + ext;
  fs.copyFileSync(fileFD,fullPath) //拷贝文件与路径

  return [`internal://cache/${fileName + '.' + ext}`,fileName + "." + ext]
}
