Comment 1 for bug 1723335

I don't think this is a duplicate.

I think this is an issue with the API server. There should be try-except block around the following lines in vnc_cfg_api_server.py:

try:
    (ok, obj_dict) = self._db_conn.dbe_read(obj_type, obj_uuid,
                                            obj_fields=['perms2'])
except NoIdError as e:
    raise cfgm_common.exceptions.HttpError(404, str(e))
