ClientLogin does not work on google appengine

[Mark Ellul]

Hi,

I am using the latest version of the Gdata python libs (v 1.2.0) with
the latest google appengine sdk.

My project is migrating a flex frontend application with a python
serverside onto google appengine. The username and password are taken
from flex and passed to my server code which authenticates using the
gdata.contacts.service.ContactsService() object (see below).

[code]
import gdata.contacts.service
import gdata.alt.appengine
gdataService = gdata.contacts.service.ContactsService()
gdata.alt.appengine.run_on_appengine(gdataService)
if(captcha_response != None):
gdataService.ClientLogin(user_name, password, captcha_token =
login_captcha_token, captcha_response = captcha_response )
else:
gdataService.ClientLogin(user_name, password)
[/code]

My main issue is that the below code works on the dev_server.py
however when I update my google appengine app, well it does not work
live. I have retrieved the exception data from below.

TypeError("object of type 'int' has no len()") in putPrefixedString()
(ProtocolBuffer.py:329) <- OutputUnchecked() (urlfetch_service_pb.py:
423) <- OutputUnchecked() (urlfetch_service_pb.py:627) <- Output()
(ProtocolBuffer.py:150) <- MakeCall() (apiproxy.py:144) <-
MakeSyncCall() (apiproxy.py:244) <- MakeSyncCall()
(apiproxy_stub_map.py:46) <- fetch() (urlfetch.py:253) <- request()
(appengine.py:115) <- ProgrammaticLogin() (service.py:449) <-
ClientLogin() (service.py:512) <- login() (iodinexmlrpcserver.py:55)

Any help would be appreciated

Regards

Mark
