我使用以下代码使用PHP启动实例：

function startInstance($g_project,$g_instance, $g_zone){

    $client = new Google_Client();
    $client->setApplicationName('Google-ComputeSample/0.1');
    $client->useApplicationDefaultCredentials();
    $client->addScope('https://www.googleapis.com/auth/cloud-platform');

    $service = new Google_Service_Compute($client);
    $response = $service->instances->start($g_project, $g_zone, $g_instance);
    echo json_encode($response);

}

今天，我很幸运地意识到，由于未知原因，我想启动的实例未能成功。我尝试使用GUI启动它，并通过GUI得到一个错误：Zone "some-zone" does not have enough resources available to fulfill the request. Try a different zone, or try again later.

我回显了PHP响应，并将其与实例成功启动时得到的响应进行了比较。我的发现令人震惊。响应完全相同（不计算时间戳和ID）。如果响应相同，我该如何区分失败的实例启动和成功？

https://cloud.google.com/compute/docs/reference/rest/v1/instances/start建议在出现error错误的情况下将存在一个对象。我可以确认没有。

两者的响应均未成功启动：
