    protected function validateGetType($haystack): string
    {
        return Str::lower(gettype($haystack));

The expression return Helldar\Support\Facades\Helpers\Str::lower(gettype($haystack)) could return the type null which is incompatible with the type-hinted return string. Consider adding an additional type-check to rule them out.
