What are you trying to achieve or the steps to reproduce?

When I try to upload my files to the server I get this error. My code on localhost works without problem, but when I run the code on the server I get this error. I want my files after upload to be on my favorite path on the server.

spawn("sudo", ["mkdir", `${tempTrim}`])
spawn("sudo", ["chown", "-R", "sigma:sigma", `${tempTrim}`])

var form = formidable({ multiples: true, maxFileSize: 700 * 1024 * 1024, keepExtensions: true});

form.on('progress', function (bytesReceived, bytesExpected) {
    console.log('PROGRESS');
    console.log(bytesReceived);
    console.log(bytesExpected);
});


form.once('error', console.error)

  
 form.on('fileBegin', function(name, file) {
       
     file.path = `${tempTrim}/${file.name}`

   })

       

        form.on('file', (filename, file) => {
            form.emit('data', { name: 'file', key: filename, value: file });
        });

        form.on('field', (fieldName, fieldValue) => {
            form.emit('data', { name: 'field', key: fieldName, value: fieldValue });
        });


       
  


        form.once('end', async() => {
            console.log('Done!');
         await zipShapeFiles()
    
        });



        form.parse(req, (err, fields, files) => {
            if (err) {
                console.error('Error', err)
                next(err)
                return

            }

What was the result you got?

What result did you expect ?

I’d expect my files to transfer to my favorite path on my server and the upload process to complete without any empty file or incomplete file.

Bunch of thanks🙏, my problem solved, I’m using html tag <form action="" method="post" enctype=enctype='multipart/form-data'> instead of fetch API and know I can upload without any error, at least not yet 😉, If I encounter dilemma again such as Abort… Or path error I’ll write here. However It seems I can launch my project the day after tomorrow without any stress and problem

You’re now getting Request aborted error. Hm.

Try using formidable-serverless, it will be integrated in v2 soon with #594
