【问题描述】：
我是 Alexa Skills 的新手，刚刚完成了 Alexa Skill Interaction Model 和 AWS 上的 Lambda 函数的连接。
我在 AWS lambda 开发者控制台上设置了一个简单的 node.js 程序，我正在使用他们的测试功能在 AWS 控制台上对其进行测试。但我不明白为什么这给了我一个错误。另外，我从示例存储库创建了这个项目 - serverlessrepo-alexa-skil-alexaskillskitnodejsfact

},

console.log(`~~~~ Error handled: ${error.stack}`);
const speakOutput = `Sorry, I had trouble doing what you asked. Please try again.`;

.getResponse();
}
};
// The SkillBuilder acts as the entry point for your skill, routing all request and response
// payloads to the handlers above. Make sure any new handlers or interceptors you've
// defined are included below. The order matters - they're processed top to bottom.
exports.handler = Alexa.SkillBuilders.custom()
.addRequestHandlers(
LaunchRequestHandler,
CaptureCoffeeIntentHandler,
HelpIntentHandler,
CancelAndStopIntentHandler,
SessionEndedRequestHandler,
IntentReflectorHandler, // make sure IntentReflectorHandler is last so it doesn't override your custom intent handlers
)
.addErrorHandlers(
ErrorHandler,
)
.lambda();
看起来 Alexa.getRequestType 没有定义。在这个过程中我有什么遗漏吗？
谢谢！
