Cloud Shell上的dev_appserver上的Google Cloud存储

我正在尝试使用GAE的Google Cloud 端存储，部署后一切正常 . 但是，我无法让存储在Google Cloud Shell上运行的开发服务器上运行 .

我正在使用cloudstorage API并且我理解dev_appserver应该访问与已部署的应用程序相同的存储桶 . 对我来说，使用本地数据也可以 .

dev_appserver.py . 调用开发服务器

我玩过没有记录的 default_gcs_bucket_name 旗帜，但没有运气 .

我使用gcloud init设置了cloud shell以使用正确的项目 . 我也尝试过使用新的 google.cloud.storage API而没有运气 .

如果我运行此处提供的示例，则会触发与下面引用的相同的错误：App Engine and Google Cloud Storage Sample .

任何人？

Edit: 无论是否提供有效或无效的存储桶名称，我都会收到相同的错误 .

的app.yaml

runtime: python27
api_version: 1
threadsafe: true

builtins:
- remote_api: on

handlers:
- url: /.*
  script: main.app

main.py

import logging
import cloudstorage as gcs
import webapp2
from google.appengine.api import app_identity

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        bucket_name = "xxxx-xxxxxx.appspot.com"     
        stats = gcs.listbucket('/'+bucket_name) 
        for stat in stats:
          self.response.write(repr(stat) + '')        

app = webapp2.WSGIApplication([
    ('/', MainPage),
], debug=True)
