Alexa Node js（alexa-app-server）response.say不输出语音

Question

I've been having some trouble trying to output speech after getting data using request-reponse and processing it. For whatever reason in the callback function it wont output the text. The console.log(prompt) works yet it the response.say(prompt).shouldEndSession(false).send() doesn't. If you've any idea it'll be greatly appreciated.

test.getNumberStatus(number, function(err, message) {
    console.log("In callback outside if statement");
    if (err == null) {
      console.log(message);
      response.say(message).shouldEndSession(false).send();
    } else {
      console.log("Error");
      rresponse.say(message).shouldEndSession(false).send();
    }
  });

stopInfo.prototype.getStopStatus = function(stopNumber, callback) {
  var options = {
  method: 'GET',
  uri: ENDPOINT + '?stopid=' + stopNumber + '&maxresults=1&format=json',
  json: true
};

requestPromise(options).then(function(stopStatusObject) {
if (true) { // check if error from dublin bus
  console.log(stopStatusObject);

  var template = _.template('busstopinfo <%= error %>');
  var message = template({
      'error': 'test'
  });
  callback(null, message);
}
}).catch(function(err) {
var message = "I didn\'t have data for stop number " + stopNumber;
callback(err, message);
});
};

I had a similar situation and found out resolve automatically sends your output which works for sync but not for async. Put add response.resolve in your troubled function to see if value is set to true before send() . If it is you already used the promise. I corrected mine by putting return in front of function name, following Asynchronous Handlers Example section from here
