Tried it using these codes but the busboy.on('file') is not triggered, I was not able to see console.log() inside busboy.on('file'), The upload is working but I want to make sure that the code inside 'file' is working and triggered

const Busboy = require('busboy');
const AWS = require('aws-sdk');
const config = require('../../config/config');
const path = require('path');
const os = require('os');
const fs = require('fs');

const s3 = new AWS.S3();

function uploadToS3(file, params) {

const fileName = file.name;
let getParams = {
    Bucket: `${config.amazon.s3.bucketName}/uploads/${params.refType}/${params.refId}`,
    Key: fileName,
    Body: file.data

s3.upload(getParams, function (err, data) {
    if (err) {
        console.log('error in callback')
    } else {


module.exports = {
upload : function(req, res, next) {

    let busboy = new Busboy({ headers: req.headers });

    busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {
        file.on('data', function (data) {
            console.log(`File ${fieldname} got ${data.length} bytes`)
        file.on('end', function () {
            console.log(`File ${fieldname} finished`)
        let saveTo = path.join(os.tmpdir(), path.basename(fieldname))

    busboy.on('finish', function() {
        console.log('upload finished');
        const file = req.files.element2;
        uploadToS3(file, req.params)




const busboy = require('connect-busboy');
