I apologize if this seems a bit unhelpful, but I’d like to mention that
I’ve never seen this error in a case where both levels of the mash were
defined. Usually what happens is I think they are, but after some
troubleshooting and researching, I notice that I’d hit a corner case in a
recipe where it wasn’t being defined as i’d expected.
I’m a little confused by your example, in that “cookbook_versions” does not
seem related to your question at hand – “cookbook_versions” set in an
environment don’t show up as an attribute on a node; but if they did, the
structure you shared would appear as something like:
node[:cookbook_versions][:sgbase] or node[:cookbook_versions][:branch].
Are you able to Chef::Log.info(node[:sgbase][:branch]) right before it’s
called there? Can you
knife node edit -a and see the expected attributes
defined (branch nested in sgbase) and saved against your node?

So I get this error:
undefined method `’ for nil:NilClass
Which comes from this line:
627>> revision node[:sgbase][:branch]
Called by a recipe in a file that does this:
“cpan”: “= 1.0.0”,
“apt”: “= 1.0.0”,
“sgbase”: “= 1.0.0”,
“branch”: “= 1.0.0”
sgbase and branch ARE defined - why the NULL error?
