undefined method to_hash for nil when missing data bags

[KAllan357]

Had this error occur when I definitely didn't have a single data bag in my Chef server. Looks like we are missing a check somewhere.

NoMethodError: artifact_deploy[foo] (foo::bar line 28) had an error: NoMethodError: undefined method `to_hash' for nil:NilClass
