Hey all,

New to puppet enterprise but trying to migrate an old puppet open source to PE and have been struggling with hiera. Maybe y'all can help...

I get this error on my test node when i try to run puppet agent -t --noop.

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, The Lookup Configuration at '/etc/puppetlabs/code/environments/production/hiera.yaml' has wrong type, entry 'hierarchy' expects an Array value, got Struct (file: /etc/puppetlabs/code/environments/production/manifests/site.pp, line: 45, column: 3) on node

Now, i'm a sys admin and I don't know much about yaml or writing their code. Maybe someone can help me a bit.

Here is my heira.yaml...

version: 5

  #  name: "Per-node data" 
    path: "nodes/%{trusted.certname}.yaml"
  #  name: "Per-OS defaults"
    path: "os/%{operatingsystem}.yaml"
  #  name: "Common Data"
    path: "common.yaml"

    data_hash: yaml_data
datadir: data

and this is my site.pp

## site.pp ##
## Active Configurations ##

# Disable filebucket by default for all File resources:
File { backup => false }

# Node definitions in this file are merged with node data from the console. See
# for more on
# node definitions.

# The default node definition matches any node lacking a more specific node
# definition. If there are no other nodes in this file, classes declared here
# will be included in every node's catalog, *in addition* to any classes
# specified in the console for that node.

node default {
  # This is where you can declare classes for all nodes.
  # Example:
  #   class { 'my_class': }

My site.pp is in my puppet controlrepo on Github located under manifests. hiera.yaml is on the top. I am trying to get my test node to pull its configs from controlrepo/data/nodes/testnode.yaml. I have another folder in controlrepo/data/os that has a CentOS.yaml file for a bunch of other stuff.

I appreciate any help. Thanks Jeff

Never mind.

I solved it by looking at the docs... hiera.yaml needs a - to make the array work

Its still not finding my nodes though.

I find it helpful to use ruby or something else to turn my yaml into json to inspect it - it makes the hash / array structure more obvious to me (someone who is less familiar with YAML)
