HarmonyOS 加载相册时设置 samepleSize，图片加载失败

加载代码如下：

let file = fs.openSync(uri, fs.OpenMode.READ_ONLY);
const imageSource: image.ImageSource = image.createImageSource(file.fd);
let imageInfo = imageSource.getImageInfoSync(0)
let decodingOptions: image.DecodingOptions = {
  editable: true,
  desiredPixelFormat: imageInfo.pixelFormat,
  sampleSize: 2,
}
try {
  //注意不加 await会报错 “Can’t return Promise in pending state”
  return await imageSource.createPixelMap(decodingOptions)
} catch (e) {
  PltLogUtil.e(“imageUtil”, “load album failed”)
  return undefined;
}
