Comment 3 for bug 1867004

The problem with the hiera command [1] is that it's returning a string.

Even enabled_services_raw.stdout_lines is a one-item-list containing a large string the characters '[' and '\"'.

u'cmd': [u'hiera', u'-c', u'/etc/puppet/hiera.yaml', u'enabled_services'], u'rc': 0, u'start': u'2020-03-11 18:36:26.245088', u'stderr': u'', u'delta': u'0:00:00.080207',
