Why can't multer see any files in my post request?

I have two node servers. One is trying to read files and the other send files. My server is set up like

.post(upload.array('test'), function (req, res) {

  if (!Array.isArray(req.files)) {
    res.status(400).json({success: false, err: 'Must have test(s))'});
    return;
  }

  var files = req.files; <-- This is always null

My Client looks like

  var http = require('request-promise');
  var request = require('request');
  var fs = require('fs');
  var FormData = require('form-data');

  var form = new FormData();

  tests.forEach(function(testName){
    form.append('test', fs.createReadStream(__dirname+'/tests/'+testName));
  });

  var options = {
      method: 'POST',
      uri: 'https://' + name +'/rest/api',
      rejectUnauthorized: false,
      timeout: 2000,
      form: form,
    };

  return http(options);

However the server is never able to find the files. The response always says err: Must have test(s).

Can anyone help me to find out what I am doing wrong in my client?

The form option is for urlencoded forms. For multipart forms you will want to set the formData option instead. Also, you don't need to explicitly use the form-data module. Example:

var requestPromise = require('request-promise');
var fs = require('fs');

var formTests = new Array(tests.length);
for (var i = 0; i < tests.length; ++i)
  formTests[i] = fs.createReadStream(__dirname + '/tests/' + tests[i]);

var options = {
  method: 'POST',
  uri: 'https://' + name +'/rest/api',
  rejectUnauthorized: false,
  timeout: 2000,
  formData: {
    tests: formTests
  }
};

return requestPromise(options);
