TypeError: str.replace is not a function

I am getting the following error:

node_modules/request/lib/querystring.js:44
  return str.replace(/[!'()*]/g, function (c) {
             ^

When I comment out:
//headers['Content-Type'] = ['application/x-www-form-urlencoded'];
it works.

This seems to be an error with the library. Maybe this can be fixed via a change of headers?

Thanks!

Yeah just remove the header. It will work fine
