The method getOption() does not exist on Zend\View\Model\ModelInterface. Did you maybe mean getOptions()?

        if (isset($fileName)) {
            if (substr($fileName, -4) != '.pdf') {
                $fileName .= '.pdf';

            $response->getHeaders()->addHeaderLine(
                'Content-Disposition',
                'attachment; filename='.$fileName);
        }
    }
