Multer MERN stack

Проблемма с загрузкой файлов через Multer

Frontend:

import React, {useState} from 'react'
import axios from "axios";

const UploadHentai = () => {
    const form = new FormData()
    const [formData, setForm] = useState({})
    const upload = async () => {
        form.append('title', formData.title)
        form.append('description', formData.description)
        await axios.post('/api/hentai/new', form)
    }
    return(
            <form onSubmit={() => upload()} encType="multipart/form-data">
                <input type="text" name="title"
                       onChange={e => setForm({...form, title: e.target.value})}
                />
                <input type="file" name="cover"
                       onChange={e => form.append('cover', e.target.files[0])}
                />
                <input type="text" name="description"
                       onChange={e => setForm({...form, description: e.target.value})}
                />
                <button type="submit">Submit</button>
        </form>
    )
}

export default UploadHentai

Backend:

const { Router }= require('express')
const multer = require('multer')
const router = Router()

const hentaiCoversFolder = 'public/hentai/covers'
const Hentai = require('../models/Hentai')
const imageMIMETypes = ['images/jpeg', "images/jpg", "images/png"]


const upload = multer({
    dest: hentaiCoversFolder,
    fileFilter: (req, file, cb) => {
        cb(null, imageMIMETypes.includes(file.mimetype))
    }
});

router.post('/search', async (req, res) => {
    try{
        const { query } = req.body
        const result = await Hentai.find({title: query.title})
        return res.status(200).json({result})
    } catch (e) {
        return res.status(400).json({msg: 'Something went wrong'})
    }
})
router.post('/new', upload.single('cover'),async (req, res) => {
    try{
        const fileName = req.file.filename

        const data = req.body
        const hentai = new Hentai({
            title: data.title,
            description: data.description,
            cover: fileName
        })
        await hentai.save()
        return res.status(200).json({hentai})
    } catch (e) {
        return res.status(400).json({msg: 'Something went wrong'})
    }
})
module.exports = router

Проблемма заключается в том что в multer приходит не изображение
