I'm making a page that displays details of an event, and details of any user that has registered an interest in coming to that event. I am using Facebook's Python-SDK (https://github.com/facebook/python-sdk) and I have had no problem getting the access token of the currently logged-in user. However, when the user visits this page of event details, the intention is that they can see names and profile pics of the users involved in this event. I use this code to populate this list of users:
for liftoffer in self.liftoffers:
if (liftoffer.user.key() == dbuser.key()):
self.hasliftoffer = True
self.template_values['myliftoffer'] = liftoffer
logging.warn("Request: fbuser = graph.get_object(%s, fields=\"name, picture, username\")" % str(liftoffer.user.fbid))
logging.warn("access_token: %s" % self.current_user.access_token)
fbuser = graph.get_object(str(liftoffer.user.fbid), fields="name, picture, username")
newuser = ListUser(fbuser['name'], fbuser['picture'], fbuser['username'], liftoffer.user.key())
self.drivers.append(newuser)
The graph has already been defined at this point using:
graph = facebook.GraphAPI(self.current_user.access_token)
Here is the error I get:

The logging lines show me that the request took in a valid Facebook ID and access_token, so I don't understand what is going wrong here. Is it not possible to get the picture and username of other Facebook users apart from the one currently logged in?
