2017-09-29 14:41:48.585 14541 ERROR neutron.api.v2.resource AttributeError: 'dict' object has no attribute 'tls_container_id'

this error caused by the code of below:

    def update_listener(self, context, id, listener):
        listener = listener.get('listener')
        curr_listener_db = self.db.get_listener(context, id)
        default_pool_id = listener.get('default_pool_id')
        if default_pool_id:
            self._check_listener_pool_lb_match(
                context, id, default_pool_id)
        self.db.test_and_set_status(context, models.Listener, id,
                                    constants.PENDING_UPDATE)
        try:
            curr_listener = curr_listener_db.to_dict()
            if 'default_tls_container_ref' not in listener:
                listener['default_tls_container_ref'] = (
                    # NOTE(blogan): not changing to ref bc this dictionary is
                    # created from a data model
                    curr_listener['default_tls_container_id'])
            if 'sni_container_refs' not in listener:
                listener['sni_container_ids'] = [
                    container.tls_container_id for container in (
                        curr_listener['sni_containers'])]

see that? error disappear when i change it like this:

 if 'sni_container_refs' not in listener:
                listener['sni_container_ids'] = [
                    container["tls_container_id"] for container in (
                        curr_listener['sni_containers'])]

we are using newton, but i found it still exists in ocata and pike
