Начало работы с Google Management API (PHP - веб-сервер) - ошибка 500

Question

Следуя документации Google для PHP-потока веб-сервера, расположенной здесь , я смог успешно запросить логин пользователя с помощью oauth2callback.php.Однако при возврате к исходному сайту после проверки подлинности возникает внутренняя ошибка сервера 500, и результаты GA не отображаются в профиле, полученном по назначению.

Как узнать, что вызвало проблему?

Примечание. Код взят непосредственно из PHP-документации Google для веб-сервера с небольшими изменениями параметров моего собственного проекта.

Трудно понять, что может быть не так с вашим кодом, если вы не отлаживаете его. Возможно, что этот код не был обновлен и библиотека была изменена. Это код из моего примера проекта, который был сгенерирован недавно. Здесь вы можете прочитать о том, как использовать образцы здесь

Oauthcallback.php

require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/Oauth2Authentication.php';
// Start a session to persist credentials.
session_start();
// Handle authorization flow from the server.
if (! isset($_GET['code'])) {
    $client = buildClient();
    $auth_url = $client->createAuthUrl();
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {
    $client = buildClient();
    $client->authenticate($_GET['code']); // Exchange the authencation code for a refresh token and access token.
    // Add access token and refresh token to seession.
    $_SESSION['access_token'] = $client->getAccessToken();
    $_SESSION['refresh_token'] = $client->getRefreshToken();    
    //Redirect back to main script
    $redirect_uri = str_replace("oauth2callback.php",$_SESSION['mainScript'],$client->getRedirectUri());    
    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
