Comment:

 [https://www.php.net/manual/en/function.setcookie.php `setcookie()`] is a
 PHP native function and never allowed the `null` value, it was just that
 PHP was tolerant about it and "juggled" `null` to the expected type.

 In other words: that code was always wrong and should be fixed.

 As of PHP 8.1,
 [https://www.php.net/manual/en/migration81.deprecated.php#migration81.deprecated.core
 .null-not-nullable-internal PHP has deprecated the tolerance for passing a
 `null` value where it is not expected or allowed].

 This has literally nothing to do with WordPress.

 Considering the phrasing of the report "I cannot pass `null` value to
 `setcookie()`", this sounds like developer error and I would like to
 suggest you keep up with changes in PHP and - as a minimum - read
 [https://www.php.net/manual/en/migration81.php the migration guide].

 If this would be a deprecation which is coming from code within WordPress,
 a backtrace is needed to find out where the offending code is.

 As things stand, however, this doesn't sound like a WP issue.

 Suggest: close.
