500 error with failed login and weird function

This error comes from failing at login, such as wrong password.

version 3.0.8.8

Uncaught ArgumentCountError: Too few arguments to function LoginWP\Core\Redirections\Redirections::login_failed_redirect(), 1 passed in /srv/www/***/public_html/wp-includes/class-wp-hook.php on line 341 and exactly 2 expected in /srv/www/***/public_html/wp-content/plugins/peters-login-redirect/

Below function in Redirections.php makes no sense. $username, $error are not used at all and when they are missing there is a fatal error.

public static function login_failed_redirect($username, $error)
{
    if (defined('DOING_AJAX') && DOING_AJAX) return;

    $disable_failed_login_redirect = loginwp_var(get_option('loginwp_settings', []), 'disable_failed_login_redirect');
    if ($disable_failed_login_redirect == 'true') return;

    $referer = wp_get_referer();
    if ($referer) {
        $referer = add_query_arg('login', 'failed', $referer);
        wp_redirect($referer);
        exit;
    }
}

should be ($username=null, $error=null) or something better.
