node.js - ENOENT: no such file or directory .?

This is error which am getting while post data and file. I have followed 'academind' tutorial for building Restful API services, also i have been searching answer for this type of errors but nothing works for me.

Am using "multer" to upload file

The folder 'uploads' available in the folder but it shows

ENOENT: no such file or directory, open 'D:projectuploads2018-01-24T07:41:21.832Zcheck.jpg'"

app.js

const express = require("express");
const app = express();
const morgan = require("morgan");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");

const productRoutes = require("./api/routes/products");

mongoose.connect('',
(err)=>{
    if(err){console.log(err)}
    else{console.log('DB Connected')}
})
mongoose.Promise = global.Promise;

app.use(morgan("dev"));
app.use('/uploads', express.static('uploads'));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.use((req, res, next) => {
  res.header("Access-Control-Allow-Origin", "*");
  res.header(
    "Access-Control-Allow-Headers",
    "Origin, X-Requested-With, Content-Type, Accept, Authorization"
  );
  if (req.method === "OPTIONS") {
    res.header("Access-Control-Allow-Methods", "PUT, POST, PATCH, DELETE, GET");
    return res.status(200).json({});
  }
  next();
});

// Routes which should handle requests
app.use("/products", productRoutes);

app.use((req, res, next) => {
  const error = new Error("Not found");
  error.status = 404;
  next(error);
});

app.use((error, req, res, next) => {
  res.status(error.status || 500);
  res.json({
    error: {
      message: error.message
    }
  });
});

module.exports = app;

product.js

const express = require("express");
const router = express.Router();
const mongoose = require("mongoose");
const multer = require('multer');

const storage = multer.diskStorage({
  destination: function(req, file, cb) {
    cb(null, './uploads/');
  },
  filename: function(req, file, cb) {
    cb(null, new Date().toISOString() + file.originalname);
  }
});

const fileFilter = (req, file, cb) => {
  // reject a file
  if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png') {
    cb(null, true);
  } else {
    cb(null, false);
  }
};

const upload = multer({
  storage: storage,
  limits: {
    fileSize: 1024 * 1024 * 5
  },
  fileFilter: fileFilter
});

router.post("/", checkAuth, upload.single('productImage'), (req, res, next) => {
  const product = new Product({
    _id: new mongoose.Types.ObjectId(),
    name: req.body.name,
    price: req.body.price,
    productImage: req.file.path 
  });
  product
    .save()
    .then(result => {
      console.log(result);
      res.status(201).json({
        message: "Created product successfully",
        createdProduct: {
            name: result.name,
            price: result.price,
            _id: result._id,
            request: {
                type: 'GET',
                url: "http://localhost:3000/products/" + result._id
            }
        }
      });
    })
    .catch(err => {
      console.log(err);
      res.status(500).json({
        error: err
      });
    });
});

module.exports = router;

in product.js:

After new Date().toISOString() add replace() to change ":" to an accepted character.

Windows OS doesn't accept files with a ":"

The person on Youtube is using MAC OS

E.g

new Date().toISOString().replace(/:/g, '-')
