Youtube api YouTube分析API+；服务访问=致命错误：未捕获异常（500）

为了执行一些CRON任务，我正在尝试使用带有服务帐户的API获取一些YouTube分析报告。我已经解决了NTP服务器同步的常见问题，显然，我已经正确设置了API控制台

    <?php

ini_set('display_errors', 1);

require_once 'gapi/src/Google_Client.php';
require_once 'gapi/src/contrib/Google_YouTubeAnalyticsService.php';

// Define constants.
const CLIENT_ID = '************************.apps.googleusercontent.com';
const SERVICE_ACCOUNT_NAME = '************************@developer.gserviceaccount.com';
const KEY_FILE = '************************-privatekey.p12';
const MY_CHANNEL = '************************';


$client = new Google_Client();
$client->setApplicationName("YouTube Analytics API Test");

session_start();
if (isset($_SESSION['token'])) {
 $client->setAccessToken($_SESSION['token']);
}

$key = file_get_contents(KEY_FILE);
$client->setAssertionCredentials(new Google_AssertionCredentials(
    SERVICE_ACCOUNT_NAME,
    array("https://www.googleapis.com/auth/yt-analytics.readonly"),
    $key)
);

$client->setClientId(CLIENT_ID);

if ($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion();
}

$token = $client->getAccessToken();

$youtubeAnalyticsService = new Google_YouTubeAnalyticsService($client);

$optparam = array("dimensions" => "country", "max-results" => "10");
$reports = $youtubeAnalyticsService->reports->query("channel==" . MY_CHANNEL, "2013-09-01", "2013-09-25", "views", $optparam);

echo $reports;
?>

有什么建议吗？提前谢谢大家

我正在调查这个问题：你是否找到任何解决方案？如果是，请告诉我。谢谢
