Upload file using multer in express.js

Question

As mentioned in the multer documentation:
https://www.npmjs.com/package/multer

We can specify the name of the uploaded file by setting "filename" in the multer.diskStorage() method.

But when I set filename, it throw this error:

Error: ENOENT: no such file or directory, open 'F:\Project\shop\public\images\image_2025-04-28T20:03:46.975Z.jpg'

and when I don't set "filename", the file is stored in the specified directory with a random name but without file extension.

How can I fix it and store files correcly (with its exstension)?
