file upload mime type issue with Multer Node.js

Question

in my project, I got to upload a Photoshop file with Multer but when I put the mime type of photoshop, wave, and mp3 files I got this error:

Error: Mime type invalide
at DiskStorage.destination [as getDestination] (C:\Users\21653\Desktop\vagaBeats\back\src\midlleware\artworkImageUploader.js:14:21)

this is my code:

 const multer = require("multer"); const path = require('path'); const MIME_TYPE_MAP = { "image/png": "png", "image/jpeg": "jpg", "image/jpg": "jpg", "file/psd": "psd" // i got a problem with this MIME TYPE }; const storage = multer.diskStorage({ destination: (req, file, cb) => { const isValid = MIME_TYPE_MAP[file.mimetype]; let error = new Error("Mime type invalide"); if (isValid) { error = null; } cb(error, path.join(__dirname, '../../', 'images/artworkImages')); }, filename: (req, file, cb) => { const name = file.originalname.toLowerCase().split(" ").join("-"); console.log(file) const ext = MIME_TYPE_MAP[file.mimetype]; cb(null, name + "-" + Date.now() + "." + ext); } }); module.exports = multer({ storage: storage }).fields([ { name: "Image"}, {name:"untagedartwork"}, {name:"psd_file"} //this is the file that i want to upload it to the server ]);

can you please help me to resolve this problem

Answer 1

Try to chage file/psd to some of this (the first one should work):

image/vnd.adobe.photoshop

application/x-photoshop

application/photoshop

application/psd

image/psd
