我们构建了一个网络应用程序，它可以根据用户定义的业务规则自动索引电子邮件附件并将其直接保存到 Google Drive。我们在同步某些 Google Drive 帐户时看到失败，并且无法找出问题所在。
这是错误：

更新：这是我们高级开发人员的实际代码。
在此处开发 (ffoeg) 添加调用的实际代码：
def list_files
pageToken = nil
params = {'maxResults' => 65535, 'q' => 'trashed = false'}
files = []
drive = session.discovered_api("drive", "v2")
while true do
call_params = pageToken.blank? ? params : params.merge('pageToken' => pageToken)
result = session.execute(api_method: drive.files.list, parameters: call_params)
if result.status == 200
files += result.data.items
break if result.data['nextPageToken'].blank?
pageToken = result.data['nextPageToken']
else
raise "List Files Error: #{result.data['error']['message']}"
end
end
files
end
再次更新：
我们更新了代码以获得确切的错误 - 这里是：
List Files Error: {"errors"=>[{"domain"=>"global", "reason"=>"backendError",
"message"=>"Backend Error"}], "code"=>503, "message"=>"Backend Error"}
