If you mean Puppet is interpreting the fact as a single string rather than
an array, then I think you are correct. Inasmuch as you have not presented
your fact code, however, I cannot tell whether yours is a structured fact
at all (so that the problem is in Puppet's handling of it), or whether it
is fundamentally a string in the first place.
If yours is indeed a structured fact, whose value in the example is a
four-element array, then your issue is probably that structured facts are
not enabled in Puppet. Agent and master must both be configured with the
'stringify_facts' option explicitly turned off (best to do this in the
[main] section of all your puppet configs). That option is *on* by default.
If yours is not actually a structured fact in the first place then in
addition to the above, you also need to rewrite the fact as a structured
one.
See the custom fact documentation
<https://docs.puppetlabs.com/facter/2.3/fact_overview.html#writing-structured-facts>
for more information.
