[chef] Re: Really? What am I missing?

[Brian Hatfield < >]

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:

NoMethodError
-------------
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:

"cookbook_versions": {
"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?
