and below is what i have tried. the productIMAGE is the filename from the react, likewise the productVIDEO

var file = [
  { name: "productIMAGE", maxCount: 10 },
  { name: "productVIDEO", maxCount: 10 },
  { name: "businessIMAGE", maxCount: 10 },
  { name: "businessVIDEO", maxCount: 10 },

var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: process.env.BUCKET,
    metadata: function (req, file, cb) {

router.post("/seller", upload.array(file), async (req, res, next) => {
  try {

    const newSeller = await new SellerAcct({
     
      city: req.body.city,
      productIMAGE: req.file.productIMAGE,

      success: true,
      message: "Seller Account Created Successful.",
      seller: {
        sellerName: seller.sellerName,
      },
    });
