Alexa LaunchRequest 无法识别指定的调用名称“星港七十五”

问题描述 投票：0回答：1

我正在阅读 Pragmatic Programmer 的《Build Talking Apps》一书，并构建我的第一个 Alexa 应用程序。

应用名称为“星港旅行”，但调用名称为“星港七十五”。这是在 en-US.json 文件中指定的，也是 Alexa 开发者控制台网站上的 invokingName。这是 Alexa 托管的技能。

问题是，在部署和构建代码后，当我尝试通过网站测试它时，通过输入“open star port 75”、“star port 75”或“star port 75”，Alexa 会做出响应：“所请求的技能响应存在问题。”

我仔细检查了区域设置为“en-US”并且应用程序使用英语。

我错过了什么？

这是我的 en-US.json 文件：

{
  "interactionModel": {
    "languageModel": {
      "intents": [
        {
          "name": "AMAZON.CancelIntent",

        {
          "name": "AMAZON.HelpIntent",
          "samples": [
            "huh",
            "what",

该响应意味着您的后端技能处理程序代码返回错误。您需要查看与该代码关联的日志以了解出了什么问题。如果该技能是 Alexa 托管的，那么您可以通过 Alexa 开发控制台中的“代码”页面访问日志，然后您将在菜单栏中看到 Cloudwatch Logs 下拉列表。可能会显示多个区域，这是选择每个区域并查看日志创建位置的情况（可能不是“默认”区域）。 如果不是 Alexa 托管，那么如果使用 AWS Lambda，请转到 Cloudwatch AWS 页面查找您的日志。
