It seems like you code against a specific sub-type and not the parent class Box\Spout\Common\Helper\FileSystemHelper as the method getRootFolder() does only exist in the following sub-classes of Box\Spout\Common\Helper\FileSystemHelper: Box\Spout\Writer\ODS\Helper\FileSystemHelper, Box\Spout\Writer\XLSX\Helper\FileSystemHelper. Maybe you want to instanceof check for one of these explicitly?

        $this->fileSystemHelper->deleteFolderRecursively($rootFolder);
    }
