如何解决 Alexa 开发人员控制台中“请求的技能响应存在问题”

Question

I'm trying to build a simple app for Alexa where user says the invocation name (voice control unity) and then say the utterance (temp world) described in custom intent (TempIntent) to get the output using buildSpeechletResponse ie(temp request). But I'm getting "There was a problem with the requested skill's response" error in Test tab in Alexa Developer Console.

I've already tried changing the intent name, invocation name, function name but nothing is working.

//This is index.js file lambda function

function onLaunch(launchRequest, session, response)
{
  var output = 'Welcome to Temp World';

  var reprompt = 'Type temp world';

  response(session.attributes,
   buildSpeechletResponseWithoutCard(output, reprompt,false));

  console.log("onLaunch requestId=" + launchRequest.requestId
    + ", sessionId=" + session.sessionId);

}

function onIntent(intent, session, response) {

   console.log("onIntent requestId=" + intent.requestId
    + ", sessionId=" + session.sessionId);

   var intent = intentRequest.intent,
    intentName = intentRequest.intent.name;

 if(intentName == 'TempIntent') {
   handleTempRequest(); 
   } 
else {
    throw "Invalid intent";
}
}


function handleTempRequest()
{

  buildSpeechletResponse("", "welcome to temp world", "", true);

}

function buildSpeechletResponse(title, output, repromptText, 
shouldEndSession) {
   return {
    outputSpeech: {
        type: "PlainText",
        text: output
    },
    card: {
        type: "Simple",
        title: title,
        content: output
    },
    reprompt: {
        outputSpeech: {
            type: "PlainText",
            text: repromptText
        }
    },
    shouldEndSession: shouldEndSession
   };
}

I expected the output to be "welcome to temp world" but the JSON output is null.

JSON Input is

"request": {
"type": "SessionEndedRequest",
"requestId": "amzn1.echo-api.request.c78c093c-eb05-4eaa-8f23-16037059e61f",
"timestamp": "2019-05-09T12:23:34Z",
"locale": "en-US",
"reason": "ERROR",
"error": {
    "type": "INVALID_RESPONSE",
    "message": "An exception occurred while dispatching the request to the skill."
   }
  }

1. Check the version of node.js you are using.
2. In the lambda function click on the test tab and test every intent, there you will find the problem.
