Uploading a file in electron programatically

[Obadah-H]

I am trying to upload a file in electron (nodejs) using plupload by file path. I tried the following methods:

const form = new FormData()
form.append('file', fs.createReadStream(filePath));
uploader.addFile(form.file)
uploader.start();

Didn't work. I also tried:

var form = {
    name: 'file1',
    file: {
      value:  fs.createReadStream(filePath),
      options: {
        filename: 'Radio.xspf'
      }
    }
};
uploader.addFile(form.file)
uploader.start();

Also didn't work. I even tried to add a form in html, and then adding a file manually, and after that add the content of the html element using:

uploader.addFile(document.getElementById('files')) //Not working
uploader.addFile($('input[type="file"]')[0]) //Not working

In all cases, the file is not being added, as console.log(uploader.files) is empty. I need to implement adding files by path programmatically. Any ideas?
