我正在 Build 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）响应会给出错误： The remote endpoint could not be called, or the response it returned was invalid.
我不知道如何弄清问题是什么或在哪里，因为我没有得到关于这个问题的任何细节 .
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 reprompt = "Would you like 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));
}
function handleGetKaiserBuildingIntent(intent, session, callback) {
var buildingType = intent.slots.Building.value.toLowerCase();
var speechOutput = "We have an error fam.";
if (buildingType != BLDG_TYPE.PHARMACY ||
buildingType != BLDG_TYPE.CLINIC ||
buildingType != BLDG_TYPE.HOSPITAL) {
speechOutput = "Please try again. I can help you find the nearest Kaiser hospital, clinic, or pharmacy.";
var repromptText = "Please try again. I can help you find the nearest Kaiser hospital, clinic, or pharmacy.";
var header = "Error fam.";

getJSON(function(data) {

你很难说你的问题是什么 . 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 .
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 .
