[chef] Re: node attribute initialized with empty array reset to nil in recipe in Chef 11

[AJ Christensen < >]

I can't reproduce with 11.4.0 and chef-shell

 => :ucanhaz_halp
chef > attributes_mode
chef:attributes > default['logstash']['join_groups'] = []
 => []
chef:attributes > recipe_mode
chef:recipe > node['logstash']['join_groups'].each do |grp|
chef:recipe >   group grp do
chef:recipe >     members node['logstash']['user']
chef:recipe ?>     action :modify
chef:recipe ?>     append true
chef:recipe ?>     only_if "grep -q '^#{grp}:' /etc/group"
chef:recipe ?>   end
chef:recipe ?> end
 => []
chef:recipe > node['logstash']['join_groups']
 => []
chef:recipe > node['logstash']
 => {"join_groups"=>[]}
chef:recipe > node['logstash'].key? 'join_groups'
 => true
