Puppet lookup fails to find hiera key value

I'm seeing this error with my puppet lookup call (basic test using hiera):

puppet lookup --explain foo

Searching for "lookup_options"
  Global Data Provider (hiera configuration version 5)
    No such key: "lookup_options"
Searching for "foo"
  Global Data Provider (hiera configuration version 5)
    No such key: "foo"
Function lookup() did not find a value for the name 'foo'

Trying a direct hiera lookup works:

hiera -d foo
DEBUG: 2019-01-16 11:53:39 +0000: Hiera YAML backend starting
DEBUG: 2019-01-16 11:53:39 +0000: Looking up foo in YAML backend
DEBUG: 2019-01-16 11:53:39 +0000: Looking for data source common
DEBUG: 2019-01-16 11:53:39 +0000: Found foo in common
bar

My hiera.yaml file (located in /etc):

---
version: 5
hierarchy:
  - name: Common
    path: common.yaml
defaults:
  data_hash: yaml_data
  datadir: data

My common.yaml file (located in /var/lib/hiera):

---
foo: bar

Can anyone explain why I'm seeing this error (fairly new to Puppet) ...

It is a file location problem.

I have:

▶ cat spec/fixtures/hiera/hiera.yaml 
---
version: 5
hierarchy:
  - name: Common
    path: common.yaml
defaults:
  data_hash: yaml_data
  datadir: data

Structure:

▶ tree spec/fixtures/hiera
spec/fixtures/hiera
├── data
│   └── common.yaml
└── hiera.yaml

Command line:

▶ puppet lookup --hiera_config=spec/fixtures/hiera/hiera.yaml foo 
--- bar

Note that the data directory as referenced in hiera.yaml in defaults.datadir must be relative to the directory your hiera.yaml is in. Ref:

datadir — The directory where data files are kept; can be omitted if you set a default.

This path is relative to hiera.yaml’s directory: if the config file is at /etc/puppetlabs/code/environments/production/hiera.yaml and the datadir is set to data, the full path to the data directory is /etc/puppetlabs/code/environments/production/data.

In the global layer, you can optionally set the datadir to an absolute path; in the other layers, it must always be relative.
