尝试代表内容所有者下载YouTube Reporting API批量报告时收到错误消息。
我已成功创建报告作业并报告作业返回下载URL，但下载失败，并显示以下错误消息：
发生服务错误：服务响应中的json无效：
日期，CHANNEL_ID，VIDEO_ID，claimed_status，uploader_type，COUNTRY_CODE，AD_TYPE，estimated_youtube_ad_revenue，ad_impressions，estimated_cpm
请有人帮我理解这个错误的含义以及如何解决问题？我在函数downloadReport中跟踪了问题。失败的一行是：
response = $client->execute($request);
我使用过Google开发人员提供的PHP示例代码： https://developers.google.com/youtube/reporting/v1/reports/#code-samples
我的“检索报告”代码的版本如下：
