You are returning a reference to an array whose content is a single hash reference. You then attempt to dereference the array as a hash. You probably mean something like this

sub passMe {
    my %data = (  # note not '{'
        ...
    );
    return \%data, $ID;
}

If you aren't getting what you expect then using Data::Dumper or YAML to print out the data structure will often help you find where the problem lies.
