hiera could not find item

[Renan Vicente]

Any one had this problem to find a attribute or know how to solve this? In my case I separated hiera files by osfamily when I execute

 # hiera packages_utils

return me

nil

BUT if I execute

# hiera packages_utils osfamily=Debian

it's works

["tzdata",
 "dnsutils",
 "bash-completion",
 "unzip",
 "bzip2",
 "htop",
 "vim",
 "ntpdate",
 "mlocate",
 "nfs-common",
 "sysstat"]

the facter osfamily works.

# facter osfamily
Debian

my hiera.yaml

# datadir is empty here, so hiera uses its defaults:

# - %CommonAppData%\PuppetLabs\hiera\var on Windows
# When specifying a datadir, make sure the directory exists.
  :datadir: /etc/puppet/hiera

my osfamily directory content

The hiera command doesn't use facter, its a tool to check the values returned by hiera in different circumstances.

How can I check this , 'Cause in my nodes I received this?

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find data item  in any Hiera data file and no default supplied at /etc/puppet/modules/ananke-base-utils/manifests/init.pp:42 on node tm-ld168-senac
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

this is the part of my code that I am having trouble:

 38 class ananke-base-utils {
 39
 40 # variables from hiera
 41
 42   $conf_file    = hiera($conf_ntp)
 43   $cpath_ntp    = hiera($conf_ntp_path)
 44   $cpath_vim    = hiera($conf_vim_path)
 45   $package_name = hiera_array($packages_utils)
 46
 47
 48 # install package based on distribuition
 49   package {$package_name:
 50     ensure         => 'present',
 51   }
 52

problem solved I just was using hiera of the wrong way, I was using hiera($conf_ntp) instead hiera('conf_ntp'), I need to provide a keyname that hiera should look up as a string.So , the error indicates that I was trying to look up a key that is stored in `$conf_ntp` and $conf_ntp is not set to a value so hiera tries to lookup an empty key.
