GuzzleHttp\Exception\ClientException: Client error: `GET https://www.bing.com/ping?sitemap=https://www.jeffgeerling.com/default/sitemap.xml` resulted in a `410 Gone` response in GuzzleHttp\Exception\RequestException::create() (line 113 of /home/geerlingguy/domains/drupal8/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php).
Every time cron runs I get this:
See issue: Bing 410 Gone.
The fix is to upgrade to the latest version of the module and enable IndexNow instead of Bing ping.
