After line 53, add this:

die "$type doesn't exist in %{\$hashref}" or isnt a hash ref unless exists $hashref->{$type} && ref $hashref->{$type} eq 'HASH';

The point is that the caller is passing $hashref, and @type_order. But one (or more) of the types in @type_order is either not a key in %{$hashref}, or the value of that key is itself not a hashref.
