Just have been running into this issue and I can confirm that this fixes compatibility with chef 14.1.

patch version bumped, ready for merge!

I see you're working on a major refactor, any chance this will get published to the supermarket before the next big release? Life is always better when you can let berkshelf handle your external cookbooks :D

Just published v0.4.1 with your fix. If you find any issue let me know.
