error: trim(): Passing null to parameter #1 ($string) of type string is deprecated #0

[stefanofornari]

I ran into the above error with latest main (below the stack trace) showing the home page with a number of albums.

adding a cast to string in line url.php:106 seems to fix the problem_

if ($path = trim((string)parse_url($uri, PHP_URL_PATH), '/'))

stack:
