Python-openid does not provide ax or sreg attributes

I was finally able to get python-openid for user authentication, but I cannot create sreg.SRegResponse or ax.FetchResponse as they are returned as None. This comes from a Google Apps account, and I try to follow the example from https://github.com/openid/python-openid/tree/master/examples/djopenid . I heard that the Google OpenID system can be a little scared and requires some settings, such as Get OpenID AX attributes from Google / Yahoo in Rails

    response = c.complete(request_args, return_to)

    sreg_response = sreg.SRegResponse.fromSuccessResponse(response)
    ax_response = ax.FetchResponse.fromSuccessResponse(response)

The answer is definitely returned as SUCCESS, but I see the following error message that may be related:

Here is my setup.

           sreg_request = sreg.SRegRequest(optional=['email', 'nickname'],
                                        required=['dob'])
            auth_request.addExtension(sreg_request)

            # Add Attribute Exchange request information.
            ax_request = ax.FetchRequest()
            # XXX - uses myOpenID-compatible schema values, which are
            # not those listed at axschema.org.
            ax_request.add(ax.AttrInfo('http://schema.openid.net/namePerson',
                                       required=True))
            ax_request.add(ax.AttrInfo('http://schema.openid.net/contact/web/default',
                                       required=False, count=ax.UNLIMITED_VALUES))
            auth_request.addExtension(ax_request)
