Fatal Error in class-sitemaps-renderer

Hi,

I’m getting a fatal error that is happening occasionally. I haven’t seen it while viewing the site, just in the logs. I just upgraded to PHP 8.0 so it may be due to that.

PHP Fatal error: Uncaught Error: Object of class WP_Error could not be converted to string in /wp-includes/http.php:683
