【问题描述】：
我正在开发一种自定义技能，但在这个意图上遇到了一些麻烦，也就是说，在 if/else 控制流中满足所有条件的最后阶段，我的意思是当它到达最后一个 else 时声明，只有这一个未能返回预期的响应，但所有返回的响应都工作得很好，我可能在这里遗漏了什么：请密切注意最后一部分 resolve(handlerInput.responseBuilder.speak....etc )。我不确定我在这里做什么，我会很感激

【问题讨论】：
-
您可以尝试打印出您收到的错误消息吗？您可以将此代码添加到会话结束请求处理程序并发布它返回的消息吗？
console.log(`Error occured: ${handlerInput.requestEnvelope.request.error.type}, ${handlerInput.requestEnvelope.request.error.message}`) -
感谢@R.Vait 的回复，因为error.type 和error.message 不是不可访问，所以显示错误，
