| In hiera 5 there is a difference between nil and empty string - both are valid as values in yaml - if that is what you are asking. As long as the backend signals "not found" as it should I think it should be possible to return both "undef" and empty string. This because you may want to be able to override some other bound value with "nothing". A user can do a type cast to String[1] to ensure they do not get undef or empty string. (but may be difficult in practice - not sure if it returns Sensitive or not). |
