I'm getting "Access Denied" trying to open a GCS file for writing. I'm using these instructions: https://cloud.google.com/appengine/docs/python/googlecloudstorageclient/read-write-to-cloud-storage. Googling not helping much. Thanks in advance. Here's my code and the error:
bucket_name = os.environ.get('BUCKET_NAME', app_identity.get_default_gcs_bucket_name()) filename = '/' + bucket_name + '/' + 'myfile' print filename gcs_file = gcs.open(filename, 'w', content_type='text/plain') ForbiddenError: Expect status [201] from Google Storage.
