在 Node-RED 中使用 Watson Assistant V2 时出现类型错误
TypeError using Watson Assistant V2 in Node-RED
我正在尝试为我正在构建的 Telegram 机器人设置 Watson Assistant。我知道我可以使用 watson-assistant-v1（即辅助节点）从 Watson 获得答案，但是，我想使用 watson-assistant-v2 （即助手V2节点）
我不知道我做错了什么。对于 Node-RED 中的 API 键，我使用的是助手的 API 键。但是，当我在调试中向机器人发送消息时，我收到“类型错误：无法读取未定义的 属性 '0'”。
我还漏掉了什么吗？为什么会出现这个错误
在Assistant V1节点中，配置的是Workspace ID。
在Assistant V2节点中，配置的是Assistant ID。
对于这两个输入文本，都应在 msg.payload 中，尽管这可以为空以允许启动对话。所以对于 V2 节点，这是一个应该有效的有效流程

如果要设置对话框，则需要设置上下文。两个节点都可以为您管理上下文，但它们需要上下文的标识符。对于 V2 节点，这是通过将 msg.params.session_id 设置为对您的应用程序有意义的任意值来完成的。例如

然后该节点会为您管理会话和上下文，并在会话到期时更新会话。
