Hi avenk
I think you just need to change from declaring *undef* to using an empty
array. The code will throw the error where the class is *NOT called* with
*$enable_ipv6_localhost
= true*,
Change:
*$my_localhost6_aliases = undef*
to
*$my_localhost6_aliases = []*
As your own code is throwing the error:
*if !is_string($my_localhost6_aliases) and
!is_array($my_localhost6_aliases) {*
* fail('hosts::localhost6_aliases must be a string or an array.')*
* }*
*undef* is not a string and it is not an array.
I hope this solves the issue for you.
