How to access req.files.location value of upload.any() object?

Question

JavaScript

Good day!
Help to display in the controller the path req.files.location of object upload.any()
routes/app.js

const express = require('express')
const upload = require('../middleware/upload')
const controller = require('../controllers/app')
const router =  express.Router()

router.post('/', upload.any(), controller.app)

module.exports = router

middleware/upload.js

const multer = require('multer')
const aws = require('aws-sdk')
const multerS3 = require('multer-s3')
const errorHandler = require('../utils/errorHandler')
const keys = require('../config/keys')

aws.config.update({
  secretAccessKey: keys.ACCESS_KEY,
  accessKeyId: keys.ACCESS_KEY_ID,
  region: keys.REGION
})

const s3 = new aws.S3();

const upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'verstesting',
    acl: 'public-read',
    key: async function (req, file, cb) {
      const today = new Date().toISOString().slice(0, 10);
      const path = "files.devices/" + req.body.id + "/" + today + "/" + file.originalname + ".jpg";
      cb(null, path);
      console.log('UPLOAD')
    }
  })
})
module.exports = upload

/controller/app.js

module.exports.app = function(req, res){
 console.log(req.files.location)  // тут то и не возвращает
}

What is quite funny, if you call upload.single('image'), then the req.file.location construct successfully displays the path where the image was saved. As I understand it, upload.any() needs to be accessed somehow differently and req.files.location does not work.
