( #3333=superdoc: print w/replies, xml ) Need Help??

Do you show me your error message? if I return undef to isa 'Str' attribute, I will see like this.

Attribute (ip_address) does not pass the type constraint because: Validation failed for 'Str' with value undef at reader test::ip_address (defined at line 7) line 15
	test::ip_address('test=HASH(0x284a2320)') called at line 35

Or, Is there some reason you can't die like this ?
sub get_ip_address { my $self = shift; my $allclasses_file = $self->allclasses_file; my $ip_address; if ( $allclasses_file =~ m/_([^_]+$)/ ) { $ip_address = $1; return $ip_address; } else { die "not good ip\n"; } }
