 Hi, I updated my server to PHP 8 and started getting errors in the debug
 log that you might want to look into. WordPress is updated so I'm afraid
 these bugs were missed. You can't pass NULL to these two functions
 anymore. Thanks.

 `PHP Deprecated:  strpos(): Passing null to parameter #1 ($haystack) of
 type string is deprecated in /wp-includes/functions.php on line 7241`
 `PHP Deprecated:  str_replace(): Passing null to parameter #3 ($subject)
 of type array|string is deprecated in /wp-includes/functions.php on line
 2187`

 Hi and welcome to WordPress Core Trac!

 #57580, #57581 and #59757 have similar reports about the
 `wp_normalize_path()` function
 ([https://core.trac.wordpress.org/browser/branches/6.4/src/wp-
 includes/functions.php?rev=56995#L2187 line 2187]), which also involves
 `wp_is_stream()`
 ([https://core.trac.wordpress.org/browser/branches/6.4/src/wp-
 includes/functions.php?rev=56995#L7241 line 7241]). The `$path` parameter
 has needed to be a string
 [https://core.trac.wordpress.org/changeset/27158/trunk/src/wp-
 includes/functions.php since the function was introduced].

 Can you determine what code is incorrectly trying to use `null` with
 `wp_normalize_path()`? If that is in a plugin, the error will need to be
 reported to its author(s).
