Cron fails if directory doesn't Exists

my cron failed to create sitemap.xml file because the directory I specified doesn't exist.

Warning: XMLWriter::openUri(): Unable to resolve file path in /domains/admin.bedfactorydirect.co.uk/http/vendor/evert/sitemap-php/src/SitemapPHP/Sitemap.php on line 165

by the above code changes the directory will be created programmatically.
