multer-s3-transform file upload is not working

I'm using multer-s3-transform to upload file to s3, but before upload I want to resize file, and save in two different size. Following is my code, no error occur, but file is not uploading.

let multer = require("multer-s3-transform");
const aws = require('aws-sdk');
const sharp = require('sharp');

aws.config.update({
  secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
  accessKeyId: process.env.AWS_ACCESS_KEY_ID
);

const s3 = new aws.S3();
var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: process.env.AWS_BUCKET_NAME,
    shouldTransform: function (req, file, cb) {
      console.log("hereeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee");
      let originalname = file.originalname;
      file.stream.once('data', async function (firstChunk) {
        let magic = firstChunk.toString('hex', 0, 4);
        let extName = path.extname(originalname).toLowerCase();
        // let filename = req.file.fieldname + '-' + Date.now() + path.extname(req.file.originalname);
        if (checkMagicNumbers(magic, extName, req)) {
          console.log("Valid File***************************");
          cb(null, true);
        }
      });
    },
    transforms: [{
      id: 'original',
      key: async function (req, file, cb) {
        let basePath = await getDynamicFilePath(req, false);
        console.log(basePath, "Path ^^^^^^^^^^^^^^^^^^^^^^^");
        let filePath = basePath;
        let filename;
        if (req.params.container === "resumes") {
          void function (req, file, callback) {
            filename = Date.now().toString() + '-' + file.originalname;
            filePath += "/cropped_" + filename;
          }()
        } else {
          filename = Date.now().toString();
          filePath += "/cropped_" + filename;
        }
        console.log(filePath, "path -------------------");
        cb(null, filePath);
      },
      transform: function (req, file, cb) {
        cb(null, sharp().resize(330, 512))
      }
    }
    {
      id: 'thumbnail',
      key: async function (req, file, cb) {
        let basePath = await getDynamicFilePath(req, false);
        console.log(basePath, "Path ^^^^^^^^^^^^^^^^^^^^^^^");
        let filePath = basePath;
        let filename;
        if (req.params.container === "resumes") {
          void function (req, file, callback) {
            filename = Date.now().toString() + '-' + file.originalname;
            filePath += "/normal" + filename;
          }()
        } else {
          filename = Date.now().toString();
          filePath += "/normal_" + filename;
        }
        console.log(filePath, "path -------------------");
        cb(null, filename);
      },
      transform: function (req, file, cb) {
        cb(null, sharp().resize(1200, 628));
      }
    }
    ]
  })
}).single("file");
upload(req, res, function (err, filePath) {
  console.log(err, "Error");
  console.log(filePath, "*************");
});

Everything is working if I use from multer-s3, except image resizing, but with multer-s3-transform no error occur, and file is not uploading, and never goes to this lines:

console.log(err, "Error"); console.log(filePath, "*************");

I have found the problem, its in following code block where I want to check file magic number.

file.stream.once('data', async function (firstChunk) {
    let magic = firstChunk.toString('hex', 0, 4);
    let extName = path.extname(originalname).toLowerCase();
    // let filename = req.file.fieldname + '-' + Date.now() + path.extname(req.file.originalname);
    if (checkMagicNumbers(magic, extName, req)) {
      console.log("Valid File***************************");
      cb(null, true);
    }
  });

If I comment this, every thing is working. It seems when taking magic number of file, file is changed to stream, and upload not work, a way to change stream back to file may work.

from multer-s3-transform file upload is not working
