Google 德语交易导致 "Sorry, I didn't get any response."

Question

我创建了 https://github.com/actions-on-google/dialogflow-transactions-nodejs 的纯德语示例。当我通过 phone（或网络模拟器）触发操作并进入第一步 "transaction_check_nopayment" 我在日志中看到调用了该方法但在客户端中我得到响应："Sorry, I didn't get any response." 可能是什么问题呢？如何更接近问题？

这是日志：

当我比较此步骤的有效英语版本和无效德语版本的日志时，我发现了不同之处：在英文日志中，每一行都以 "transactions hyd4scvzft31" 结尾。我在德语日志中错过了这一部分。但是，在我的德语应用程序的配置中，我也回答 "Does your app perform Transactions?" 是。

在 transaction_check_nopayment 的例子中 app.askForTransactionRequirements() 被调用。德语可能不支持 askForTransactionRequirements() 吗？是否有 transaction-API 的概述记录了支持的语言？交易 API 是否适用于德国用例？作为付款方式，我有发票。当我理解文档时，这就像在 google-API 中没有付款一样。

Answer 1

隐藏在 Policies and Terms > Other > Special Requirements for Certain Use Cases、Google 状态下 'Currently, the Transactions API is only available in the United States; apps in other countries cannot implement the API or complete transactions until the API is available there.'
