Nodejs problem when uploading image to the server with 'formidable'


Hi, I'm trying to upload a file, in my case it will mostly be an image or images in a director of my backend made in nodejs, then I leave the code of the function that subverts the image with formidable :'/uploadImage', (request, response) => {
    const form = new formidable.IncomingForm()
    const address = path.dirname(__filename).split('/')

    form.uploadDir = '../imagenes/'; //path donde guardaras la imagines
    form.keepExtensions = true; //mantener las extensiones
    form.maxFieldsSize = 10 * 1024 * 1024; //10MB
    form.multiples = true; //multiples archivos

    form.parse(request, (err, fields, files) => {
        if (err) {
                message: 'error al subir la imagen',
                data: []

        const { upload } = files //Hacemos Destructuring, por lo que equivale a 'const upload = files.upload'
        let data

        if (upload) { //Si existe archivo subido o no
            let filesPath

            if (Array.isArray(upload)) { //Si se han subido mas de un archivo, es decir, si es un Array de archivos
                filesPath = => file.path)
            } else {
                filesPath = upload.path

            data = {
                message: 'imagen subida correctamente !!',
                data: filesPath, //Devolvemos una o la lista de rutas de los archivos
                numImagenes: upload.length //Devolvemos la cantidad de archivos
        } else {
            data = {
                message: 'No hay ninguna imagen seleccionada para subir .. ',
                data: [],
                numImagenes: 0


Below I show what the server returns to me when using postman to test whether it works or not, and this is what it says to me:
