测试Facebook Business-SDK时出错

如何解决测试Facebook Business-SDK时出错

我从PHP的Facebook业务SDK开始。正在关注此文档：https://developers.facebook.com/docs/business-sdk/getting-started/ 安装没有问题，然后按照他们的指示尝试测试， 创建了src / test.PHP

<?PHP
require_once __DIR__ . '/../vendor/autoload.PHP';
use FacebookAds\Api;
use FacebookAds\Logger\CurlLogger;
use FacebookAds\Object\AdAccount;
use FacebookAds\Object\Campaign;
use FacebookAds\Object\Fields\CampaignFields;

$app_id = "{app-id}";
$app_secret = "{appsecret}";
$access_token = "{access-token}";
$account_id = "act_{{adaccount-id}}";

Api::init($app_id,$app_secret,$access_token);

$account = new AdAccount($account_id);
$cursor = $account->getCampaigns();

// Loop over objects
foreach ($cursor as $campaign) {
  echo $campaign->{CampaignFields::NAME}.PHP_EOL;
}

填写必需的值。并运行文件。得到这个：

FacebookAds\CrashReporter : Enabled
FacebookAds\CrashReporter : Exception detected!
FacebookAds\CrashReporter : Successfully sent report

不确定我在做什么错。通过搜索找不到很多东西。谁能帮忙吗？
