Unhandled rejection TypeError: expecting an array or an iterable object but got [object Null]

The 3.0.0 upgrade seems to have broken my web scraper. I get the following error message when trying to run this code:

I've deleted the node_modules directory and reinstalled all modules, as well as creating a new project with barebones code. The issue still persists, but disappears after I roll back bluebird to v2.10.2.

promisify no longer converts multi-argument callbacks to promises for arrays. This will break every single promisify call on request :(

Use the new multiArgs option when promisifying request. Let us know if it fixes the problem

It looks like I've got some reading & experimenting to do tonight. Thanks for letting me know.
