chef_gem[treetop] (dynamically defined) had an error: NoMethodError: undefined method `full_name' for nil:NilClass

[runningman84]

I am unable to use chef-solo-search behind a http proxy. I tried to configure the proxy in the vm_aws recipe:

ENV['http_proxy'] = "http://192.168.99.5:3128/"
ENV['https_proxy'] = "http://192.168.99.5:3128/"
Chef::Config[:http_proxy] = ENV['http_proxy']

but I get this error

this looks like an issue related to installing the treetop gem. I couldn't repro. Halp?

[benlangfeld]

All that's required is a ubuntu bento box and including chef-solo-search in the runlist, you'll see this occur very readily. Unfortunately this makes this cookbook entirely useless right now, and I'm not sure what the solution is.

I note this cookbook doesn't have test-kitchen setup. I'll add it and submit a PR for an easy demo of this issue.
