Trying to upload multiple image file using Formidable in node.js

Question

I am trying to upload multiple image file in node.js using formidable so error is in accessing the path property of fields in formidable

here is my app.js code

app.post('/',(req,res)=>{
    const form = formidable({ multiples: true });
    form.keepExtensions = true;
    form.parse(req, (err, fields, files) => {
      if (err) {
          return res.status(400).json({
              error: "Image could not be uploaded"
          });
      }
      // check for all fields
      const {noi} = fields 
      
      let user = new User(fields);
      console.log(noi)
      console.log(files.img[0])
      
      //console.log(files.img.path)

      // 1kb = 1000
      // 1mb = 1000000

      l = noi // noi -> number of images 
      var  i = 0
      // to checck the number of image file user want to upload
       for(i=0 ; i < l; i++ )
       {
         if (files.img) {
             // console.log("FILES PHOTO: ", files.photo);
             
             
             user.img[i].data = fs.readFileSync(files.img[i].path);
             user.img[i].contentType[i] = files.img[i].type;
         }
       }

      user.save((err, result) => {
          if (err) {
              return res.status(400).json({
                  error: errorHandler(err)
              });
          }
          res.json(result);
      });
  });
  
})

the output for console.log(files) is :

{
  img: [
    File {
      _events: [Object: null prototype] {},
      _eventsCount: 0,
      _maxListeners: undefined,
      size: 7682,
      path: 'C:\\Users\\kushw\\AppData\\Local\\Temp\\upload_106d6e0c756a00460b552208b5ac8004.jpeg',
      name: 'download.jpeg',
      type: 'image/jpeg',
      hash: null,
      lastModifiedDate: 2021-10-18T14:03:29.718Z,
      _writeStream: [WriteStream],
      [Symbol(kCapture)]: false
    },
    File {
      _events: [Object: null prototype] {},
      _eventsCount: 0,
      _maxListeners: undefined,
      size: 7571,
      path: 'C:\\Users\\kushw\\AppData\\Local\\Temp\\upload_be8b426dec71c4ead1cd07ee2f97a03a.jpeg',
      name: 'download1.jpeg',
      type: 'image/jpeg',
      hash: null,
      lastModifiedDate: 2021-10-18T14:03:29.721Z,
      _writeStream: [WriteStream],
      [Symbol(kCapture)]: false
    }
  ]
}

the error I am getting is :

  user.img[i].data = fs.readFileSync(files.img[i].path);
                              ^

TypeError: Cannot set property 'data' of undefined

So what I understood is I need to access the path in img, I tried many ways but not able to read that property.

my model is :

const mongoose = require('mongoose');

const userschema = new mongoose.Schema({
    noi: Number,
    
    img:[{
      data:Buffer,
    type:  String
  }] 
  });

module.exports = mongoose.model('User', userschema);

thanks
