Basically, Windows OS file don't accept ":" named. He used Mac OS. so you have to add .replace(/:/g, '-') in front of new Date().toISOString() that is:

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

I hope it solves your problem too :)

Solution 2:

I've been through the same issue, the answer for this is given in the FAQ section of the course.Still if you're not getting it follow the next steps..

Install uuid package using: npm install --save uuid require using: const { v4: uuidv4 } = require('uuid')

Rewrite your code as:

const fileStorage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, 'images');
},
 filename: (req, file, cb) => {
cb(null, uuidv4() + '-' + file.originalname);
}
});

I hope this will solve your issue too. Thank-you :)

Solution 3:

Use uuid for this instead of newDate().toIsoString()

const fileStorage = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, 'images');
    },
    filename: (req, file, cb) => {
        cb(null, uuidv4() + '-' + file.originalname);
    }
});
