In kotlin implementation, configuration is sent to server ( see https://github.com/theopenconversationkit/tock/blob/c67acb344df09b1b96c2ca81af428ebd0a09d058/bot/api/websocket-base/src/main/kotlin/BotApiWebSocketClient.kt#L134 ) But there is no such action in node implementation. The consequence is that no built-in story is persisted on server side, causing subtle bugs.
