TypeError: formData.hasOwnProperty is not a function

[52cik]

When formData is created by Object.create(null), the bug is triggered.
Ps: express req.body object is such objects.

const request = require('request');

const formData = Object.create(null);
formData.test = 'test';

request.post({ url: 'http://localhost:3000', formData: formData }, function(err, res, body) {
  if (err) {
    return console.error('upload failed:', err);
  }
  console.log('Upload successful!  Server responded with:', body);
});

$ node app.js
/Users/cik/Desktop/bug/node_modules/request/request.js:330
      if (formData.hasOwnProperty(formKey)) {
                   ^

Chaging formData.hasOwnProperty(formKey) to Object.prototype.hasOwnProperty.call(formData, formKey) should fix this
