    },
  });

  sharpImage.keepMetadata();

  sharpImage.keepExif();

  const buffer = await sharpImage.toBuffer();

  const { exif } = await sharp(buffer).metadata();

  console.log(exif?.toString());

  try {
    if (exif !== undefined) {
      console.log(exif.toString().substring(0, 2) === "II");
      console.log(ExifReader.load(exif));
    }
  } catch (err) {
