为什么要采取行动。意图是否未触发事务\u决策?

我想创建一个带有Dialogflow和Google Assistant以及Google Transactions API的聊天机器人,让用户能够订购一些物品。目前,我的代理包含以下四个意图:

• Default Welcome Intent (短信回复:你好,你想买巧克力盒吗?)
• Default Fallback Intent
• Int3 (培训短语:Yes,I want,performation:enabled webhook)
• Int4 (事件: actions_intent_TRANSACTION_DECISION ,实现:启用webhook)

我使用的是Dialogflow Json,而不是Node。js将我的代理与事务API连接起来。我想通过使用finally为用户构建购物车和订单,以确保用户通过使用 actions.intent.TRANSACTION_DECISION 谷歌行动的行动。因此,在谷歌文档之后 Int3 我正在使用一个webhook连接Google Assistant我的后端,它会发回以下json(用于触发 行动。意图交易决策 ) :

请注意,我实际上是在复制粘贴Google文档中的JSON。

然而 Int4 未触发,这意味着 行动。意图交易决策 也不会触发。

我只在谷歌助手(当 Int3 触发,并从我的后端将上述json作为响应发送)以下消息/错误:

Sorry, something went wrong. Please try again later.

因此,我无法真正理解json中的错误及其原因 行动。意图交易决策 未触发。

为什么? 行动。意图交易决策 是否未触发?上面的json是否有未发现的问题?

我不知道我的问题是否与此有关: Actions on Google returns in simulator "We're sorry, but something went wrong. Please try again." .然而,我测试了此链接中所有可能的解决方案,到目前为止,没有任何解决方案真正适合我。 另外,请记住,我已经触发了Google Transactions API的所有其他内置意图( actions.intent.TRANSACTION_REQUIREMENTS_CHECK ,则, actions.intent.DELIVERY_ADDRESS ,则, actions.intent.SIGN_IN )它们都可以与我的代理/应用程序配合使用。只是出于某种原因 行动。意图交易决策 返回此错误( Sorry, something went wrong. Please try again later. )对我来说。
