FATAL: NoMethodError: undefined method `[]' for nil:NilClass

Please help me, this seems to be there consistently with my recipe. Its been a week since i have been compiling but no luck so far.

All that i am trying to pick is file from artifactory

remote_file "citrixvda" do

source "#{node.default['gapinc-citrix-agents']['windows_source']}/#{node.default['VDAServerSetup_2006']['windows_pkg']}"

headers artifactory_basic_auth

#headers( "Authorization"=>"Basic #{ Base64.encode64("#{artifactory_user}:#{artifactory_passwd}").gsub("\n", "") }" )

path "C:\agents\#{node.default['VDAServerSetup_2006']['windows_pkg']}"

checksum "#{node.default['VDAServerSetup_2006']['checksum']}"

action [:create]

not_if { ::File.exists?("C:/agents/#{node.default['VDAServerSetup_2006']['windows_pkg']}") }

sensitive true

ignore_failure true

end

here is trace from my vagrant: Please help me !
