Google App Script UnauthorizedException：您需要获得许可

Question

我正在关注示例here。它运作良好。但是在客户端，我试图在将数据发布到Google工作表之后立即从我的PHP服务器获得响应。如果我不删除下面的代码块，它运行良好，我得到print_r作为返回的数据（响应）。如果我删除下面的代码块，我会在Chrome DevTools上获得500（内部服务器错误）。我不知道是什么问题。谢谢你的帮助！

$listFeed = $worksheet->getListFeed();
foreach ($listFeed->getEntries() as $entry) {
           $representative = $entry->getValues(); 
           print_r($representative);  
} 

当我打印heroku日志时，我收到错误：
