Google Drive API导出使用application / zip MIME获取空内容

Question

I have this code:

// v2.2.1 Client library for Google APIs
// [https://github.com/google/google-api-php-client]

$client = new Google_Client(); 
$client->setAuthConfig(CONFIG_FILE);
$client->setScopes(array(
    Google_Service_Drive::DRIVE,
    Google_Service_Drive::DRIVE_READONLY,
));
$service  = new Google_Service_Drive($client)

// Test file, Spreadsheets
$response = $service->files->get('1GDeQU7mVbipmQlPTTccmznUeJ0AgFyNrGA4TfzTgEys');

$download = $service->files->export($fileId, 'application/zip', array('alt' => 'media'));
$content = $download ->getBody()->getContents();

Until last week I have in $content the zipped html file (as written in the documentation), but now the variable is empty even if the $download object return statusCode 200 (success).

If I change application/zip to application/pdf the file is downloaded correctly (obviously in pdf format), so I think there aren't problems on file permissions.

The file is a Spreadsheets.

What am I doing wrong?

Thanks

Edit:

I think it's a bug, it does not even work with the explorer APIs.

The bug seems to be solved, now the files are downloaded without errors.
