I have been seen this : NodeJS Multer validate fields before upload but is not work. i tried for make validate field before upload in a days and the result is not working. is it because mutler can't do this?

Iam using MERN : MongoDB,React,Express,Node

i want validate this data in Form-data : dataMurid before uploading the image.
is there another way to overcome this? Maybe using other library? and please give me exampale code.

Route

// @route buat edit/create murid baru
router.post('/datasiswa/create',(req, res,next) => 
 upload(req,res,(err)=>

 let request = JSON.parse(req.body.newMurid);
 // upload(req.body.data.data, res, (err) => 
 // console.log(req.body.data.data);
 // );
 const errors, isValid = validateMuridInput(request);

 // Check validation
 if (!isValid) 
 return res.status(400).json(errors);
 
 const muridFields = ;
 if (request.tempatLahir) muridFields.tempatLahir = request.tempatLahir;
 if (request.jenisKelamin) muridFields.jenisKelamin = request.jenisKelamin;
 if (request.nis) muridFields.nis = request.nis;
 if (request.nama) muridFields.nama = request.nama;
 if (request.tanggalLahir) muridFields.tanggalLahir = request.tanggalLahir;
 if (request.namaAyah) muridFields.namaAyah = request.namaAyah;
 if (request.namaIbu) muridFields.namaIbu = request.namaIbu;
 if (request.noTelepon) muridFields.noTelepon = request.noTelepon;
 if (request.hpSiswa) muridFields.hpSiswa = request.hpSiswa;
 if (request.hpIbu) muridFields.hpIbu = request.hpIbu;
 if (request.hpAyah) muridFields.hpAyah = request.hpAyah;
 if (request.alamat) muridFields.alamat = request.alamat;

 Murid.findOne( nis: request.nis )
 .then((murid) => 
 if (murid) 
 errors.nis = 'NIS ini sudah terdaftar';
 return res.status(400).json(errors);
 else 

 const newMurid = new Murid(muridFields);

 newMurid.save()
 .then((murid) => 
 res.json(murid);
 )
 .catch((err) => 
 console.log(err);
 );


 
 )
 );


);

Upload func

const multer = require('multer');
const path = require('path');

// UPLOAD IMAGE

// Set Storage engine
const storage = multer.diskStorage(
 destination: './public/uploads/',
 filename: function (req, file, callback) 
 callback(null, file.fieldname + '-' + Date.now() + path.extname(file.originalname));
 
);

// Init upload 
let upload = multer(
 storage: storage,
 limits:fileSize:1000000, //file size dalam bit
).fields([ name: 'fotoDisplay' , name: 'newMurid' ]);

With multer, in your req.file, you have all the fields about the file.

var multer = require('multer')
 var upload = multer( dest: 'uploads/' )
 import fs from 'fs-extra'

 router.post('/register', upload.single('avatar'), (req, res, next) => 
 return fs.readFile(req.file.path)
 .then(content => 
 // The content of the file
 )
 

req.file has the mimetype and so much more that you can check
