HttpError 502与谷歌Wave主动机器人API fetch_wavelet（）

我尝试使用谷歌Wave主动机器人API fetch_wavelet()，我得到一个HTTP 502错误HttpError 502与谷歌Wave主动机器人API fetch_wavelet（）

例如：

from waveapi import robot 
    import passwords 

    robot = robot.Robot('gae-run', 'http://images.com/fake-image.jpg') 
    robot.setup_oauth(passwords.CONSUMER_KEY, passwords.CONSUMER_SECRET, server_rpc_base='http://www-opensocial.googleusercontent.com/api/rpc') 
    wavelet = robot.fetch_wavelet('googlewave.com!w+dtuZi6t3C','googlewave.com!conv+root') 
    robot.submit(wavelet) 
    self.response.out.write(wavelet.creator)

但这个错误我得到的是：

Traceback (most recent call last): 
    File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/__init__.py", line 511, in __call__ 
    handler.get(*groups) 
    File "/base/data/home/apps/clstff/gae-run.342467577023864664/main.py", line 23, in get 
    robot.submit(wavelet) 
    File "/base/data/home/apps/clstff/gae-run.342467577023864664/waveapi/robot.py", line 486, in submit 
    res = self.make_rpc(pending) 
    File "/base/data/home/apps/clstff/gae-run.342467577023864664/waveapi/robot.py", line 251, in make_rpc 
    raise IOError('HttpError ' + str(code)) 
IOError: HttpError 502

任何想法？

编辑：

当[email protected]不是波我得到正确的错误消息的成员

Error: RPC Error500: internalError: [email protected] is not a participant of wave id: [WaveId:googlewave.com!w+Pq1HgvssD] wavelet id: [WaveletId:googlewave.com!conv+root]. Unable to apply operation: {'method':'robot.fetchWave','id':'655720','waveId':'googlewave.com!w+Pq1HgvssD','waveletId':'googlewave.com!conv+root','blipId':'null','parameters':{}}

但当[email protected]为波我得到的HTTP成员502错误。
