Getting undefined local variable error when running cookbook

[slbailey]

I'm running the cookbook using chef-solo as part of a packer deployment and I'm getting an error that I'm sure is my stupidity but I can't figure out what's wrong:

It would appear the resource in the cookbook is a victim of a breaking change in chef-client 14.x, which requires that properties are referenced with new_resource.propertyname.

It works fine under chef-client 13.x
