IBM Watson Assistant / Conversation：输出显示上次搜索

Question

我开发了云功能，并且正在使用 'generic output' 图像响应类型，以及文本。但是，当我搜索产品（使用我的云功能）时，会出现最后的结果。

例如：

Me: Buy Classic now

Bot: Name: Classic, Price: 4.99, Description: Classic description

但是当我搜索其他产品时

Me: Buy Extra now

机器人将显示

Bot: Name: Classic, Price: 4.99, Description: Classic description

直到另一个搜索实例才会刷新并显示正确的结果。

找到答案了。我将输出文本放在子节点而不是父节点中。无需删除任何上下文变量。
