multer: Multer diskStorage destination errors on production environment

Hello,

On development environment code below works properly but on production nothing works.When I opened logs there are this error: Error OccuredError: ENOENT: no such file or directory, open ‘public/images/8c3f666974_kiwi.png’.2 days I am trying to resolve it but… no result I try many things read many articles but nothing … What is the problem?I read all multer documentation and I think I am implementing it properly?

This is code:

const express = require("express");
const router = express.Router();
const multer = require('multer');
const db = require("../connection/databaseConn");
const Product = require("../models/Product");
const encryption = require("../encryption/encryption");
const path = require('path')

let storage;
let upload;

router.get("/upload",(req,res)=>{

    res.render("upload");

});
 
let imagesNames = [];

new Promise((resolve, reject)=>{
  resolve(
    storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null,"public/images/")
  },
  filename: function (req, file, cb) {

    let imageId = encryption.generateId();
    let imageNameWithId = imageId.substr(0,10);
    imagesNames.push({name:imageNameWithId,id:imageId});
    let fileName = "" + imageNameWithId + "_" + file.originalname;

    cb(null, fileName)
  }
}))

}).then((storage)=>{
  upload = multer({storage:storage}).any();
})
  
router.post('/upload', function(req, res) {
   
    upload(req, res, function(err) {

      if(err) {
        console.log('Error Occured' + err);
          return;
        }
        let files = req.files;

        
      Product.findById(req.session.productId).then((p)=>{
          for(let i = 0; i < files.length;i++){

            p.images.push({imageId:imagesNames[i].id,imageName :"/static/images/" + imagesNames[i].name + "_"  + files[i].originalname});
                        
          }

          p.save();

      }).then(()=>{

            req.session.addMessage = "Product created!";
            res.redirect("/categoriesLoad");

       });
  })
    
});

module.exports = router;
