Hello,

i assume your host_groups is an array. Then the only filter that will work is like "\"linux-servers\" in host.groups" }', No regex or wildcard is allowed/useable here.
If you want to do a regex or match you have to create a (string) variable like vars.string_host_groups = groups.to_string().

Carsten
