Google cloud Storage 308 Error while writing file

Hi All, I tried to pull the report from Double Click Search API and put it into Google Cloud Storage by using google app engine(Python).

The following code is used to pull the report and place in google cloud storage.

If I hard code the report_run_id in ds_check_status_report it is writing the file properly but when I try to pull the report_run_id from bigquery and pass then it is throwing 308 error.

class ds_check_status_report(webapp.RequestHandler):

    _apptitle      = None
    _projectid     = None
    _projectnumber = None

    def get(self):
        cfg=appsettings()
##      report_run_id="kdajdsjflsjfl"  
        result=dsbqfuns._dsbqquery()
        result1=json.dumps(result['stacktrace'])
        res=json.loads(result1)
        self.response.write(res['rows'][0]['f'][0]['v'])
        dsutils.poll_report(res['rows'][0]['f'][0]['v'])

def poll_report(report_id):
  """Poll the API with the reportId until the report is ready, up to ten times.

  Args:
    service: An authorized Doublelcicksearch service.
    report_id: The ID DS has assigned to a report.
  """
  print "Enter into poll_report"
  cfg=appsettings()
  creds = create_credentials(cfg._client_id , cfg._client_secret, cfg._refresh_token)
  service = get_service(creds)
  try:
    request = service.reports().get(reportId=report_id)
    json_data = request.execute()
    if json_data['isReportReady']:
      print('The report is ready.')

      # For large reports, DS automatically fragments the report into multiple
      # files. The 'files' property in the JSON object that DS returns contains
      # the list of URLs for file fragment. To download a report, DS needs to
      # know the report ID and the index of a file fragment.
      for i in range(len(json_data['files'])):
        print('Downloading fragment ' + str(i) + ' for report ' + report_id)
        download_files(service, report_id, str(i)) # See Download the report.

    else:
      print('Report is not ready. I will try again.')

  except:
    exc_type, exc_value, exc_traceback = sys.exc_info()
    print exc_type, exc_value, exc_traceback

  request = service.reports().getFile(reportId=report_id, reportFragment=report_fragment)
  gcs_file.write(request.execute())
  gcs_file.close()
