Answer

Are you working on a local server/localhost?

/errors.php will refer to your base url, e.g. http://localhost/errors.php. If you are working with a project directory (e.g. http://localhost/project_dir/), the path to the errors.php-file should be /project_dir/errors.php.

With this change, the code works fine on my system.
