Why doesn't the request body look 'normal'?

My form code:

var form = new FormData();

form.append(project.name+'.zip', fs.createReadStream("/"+project.name+'.zip'));
form.submit({
    host: 'http://host.mysite.dev',
    path: '/api/v1/prototypes',
    headers: {
      'Authentication': 'secret'
    }
  }, function(err, res) {
    if(err) console.log("ERR: ", err)
    else console.log("RES: ", res)
    console.log(res.statusCode);
  });

My backend is expecting the request to look like this (tested with postman).

------WebKitFormBoundarywo69VE86H8vMc9ah
Content-Disposition: form-data; name="attachment"; filename="basic.zip"
Content-Type: application/zip

Instead, my request looks like this crazyness which rails can’t interpret as a file. I have no idea how to make a normal multipart form request with node.

Hi guys, I bumped into this discussion while debugging an integration with Tableau REST API. I also was expecting to see a text body request instead of a stream. I fear this is what might be causing my request not to be accepted in the API (all rest seems to be formatted fine). Is there anyway we can avoid using stream/buffers to chunk the data being passed in the request ?

Yep.

@erikmellum feel free to add more details and reopen the issue if you want to continue this discussion. Thank you.
