javascript - 将原始图像和带水印的图像上传到 aws s3 存储桶的问题

Question

我正在为我的项目开发功能，将输入的图像上传到 aws，使用 jimp 为其添加水印，然后将带水印的图像上传到 aws。所有功能都有效，但是，只有预加水印的图像被上传两次，而加水印的图像似乎在上传到 aws 后更新。我相信它与异步有关并且使用了 Promise，但由于我是 js 新手，我不太确定我是否遗漏了一些明显的东西。我在下面附上了我的三个功能。

 const uploadFile = async (fileName) => {
  //Read content from file
  const fileContent = fs.readFileSync(fileName);

  //setting up S3 upload parameters
  const params = {
    Bucket: BUCKET_NAME,
    Key: 'original_test.jpg', //filename to save as in S3
    Body: fileContent,
  };

  //uploading image to the bucket
  s3.upload(params)
    .promise()
    .then((data) => {
      console.log('Success');
      watermarker(fileName);
    })
    .catch(function(err) {
      console.log(err);
    });
};



 const watermarker = async (uploadedImage) => {
  const promises = function jimpify() {
    return Jimp.read(uploadedImage)
      .then(function(image) {
        loadedImage = image;
        return Jimp.loadFont(Jimp.FONT_SANS_128_BLACK);
      })
      .then(function(font) {
        loadedImage.print(font, 10, 10, imageCaption).write(uploadedImage);
      })
      .catch(function(err) {
        console.error(err);
      });
  Promise.all(promises).then(() => watermarkImageUploader(uploadedImage));
};



 const watermarkImageUploader = async (watermarkedImage) => {
  //Read content from watermark image
  const watermarkFileContent = fs.readFileSync(watermarkedImage);

  //watermark image S3 upload parameter
  const watermarkParams = {
    Bucket: BUCKET_NAME,
    Key: 'watermark_test.jpg', //filename to save as in S3
    Body: watermarkFileContent,
  };

  //uploading watermark image to the bucket
  s3.upload(watermarkParams)
    .promise()
    .then(function(data) {
      console.log('Success 2');
    })
    .catch(function(err) {
      console.log(err);
    });
};
