PHP Warning: Undefined array keys in /wp-includes/canonical.php

Hello,

I am seeing the following errors in the error_log on my website’s server:

[27-Sep-2022 23:04:03 UTC] PHP Warning: Undefined array key “host” in /home/…/public_html/wp-includes/canonical.php on line 699
[27-Sep-2022 23:04:03 UTC] PHP Warning: Undefined array key “scheme” in /home/…/public_html/wp-includes/canonical.php on line 720

I’m not sure how to go about resolving these errors. Any help would be greatly appreciated.
