Question

我正在建立一个Alexa技能，告诉用户最近的Kaiser Permanente医院，诊所或药房。当我使用三个关键字之一进行测试时，出现错误：The response is invalid.

给出无效（不使用三个关键字）回复会给我一个错误：The remote endpoint could not be called, or the response it returned was invalid.

我不知道如何找出问题的内容或位置，因为我没有得到有关该问题的任何细节。

function getWelcomeResponse(callback) {
  var speechOutput = "Welcome to the Kaiser Permanente Alexa Skill. Allow me to help you find the nearest Kaiser hospital, pharmacy, or clinic.";

  var header = "Kaiser Permanente Skill";
  var shouldEndSession = false;
  var sessionAttributes = {
    "speechOutput" : speechOutput,
    "repromptText" : reprompt,

  callback(sessionAttributes, buildSpeechletResponse(header, speechOutput, reprompt, shouldEndSession));

Answer 1

很难说出你的问题是什么。它可能是一个不正确上传的Lambda函数，或者您的JSON响应可能太大，因此达到了响应大小限制。解决此问题的最佳方法是查看Cloudwatch中的错误日志，看看它的内容。

Answer 2

您还可以尝试在GET请求返回时返回一个简单的硬编码字符串，以确保到目前为止的所有内容都能正常工作。然后用响应中的数据替换硬编码字符串。
