 I have WordPress 6.8-beta3-60069 with PHP 8.3 installed.

 When I use `get_post_meta()` with a not existing beta key for the current
 post the warning

   Warning: Undefined array key 0 in wp-includes\meta.php on line 651

 appears.

 This messages is realted to `return $check[0];`
 `$check` is an array, but empty. Thats why the key `[0]` does not exist.

 You can check with a random request

 `$duration = get_post_meta( $post_id, 'random_key', true );`
