Comment (by jojooba008):

 I tried running your script and got the error as well.
 However, the message seems to be a little different from yours...?

 {{{
 [28-Jul-2022 09:53:59 UTC] PHP Notice:  Undefined index: host in /xxxxx
 /wp-includes/canonical.php on line 687
 [28-Jul-2022 09:53:59 UTC] PHP Notice:  Undefined index: host in /xxxxx
 /wp-includes/canonical.php on line 696
 [28-Jul-2022 09:53:59 UTC] PHP Notice:  Undefined index: host in /xxxxx
 /wp-includes/canonical.php on line 699
 }}}

 I also tried running it with "http1.0" as "http1.1" and this time no error
 appears.

 their blog?
