Alexa应用程序在本地工作，在Lambda上提前返回

Question

因此，当我在本地运行时，我有多个调用链接在一起工作，并将更新发布到google电子表格，但当我尝试在Lambda上运行它时，它只是提前返回，没有任何错误。

skillService.intent("sampleIntent", {
        ...
    },
    function(request,response){
        var name = request.slot("NAME");
        var category = request.slot("CATEGORY");
        var event = request.slot("EVENT");

        // slot used for any parts of conversation
        var stepValue = request.slot('STEPVALUE');

        var sampleHelper = getHelper(request);
        // If it hasn't started, see if the user gave some slots and start from that step
        if(!sampleHelper.started){
            sampleHelper.determineStep(name, category, event);
        }
        sampleHelper.started = true;
        // Did they provide all the necessary info?
        if(sampleHelper.completed()){
            // Handles reading out the menu, etc
            return sampleHelper.updateSheet(response);
        }
);

下面是updateSheet的外观

SampleHelper.prototype.updateSheet = function(resp){
    var name = this.observance[0].steps[0].value;
    var category = this.observance[0].steps[1].value;
    var event = this.observance[0].steps[2].value;
    console.log("about to auth.");
    return authorize(JSON.stringify(this.access_token))
        .then(function(auth){
            console.log("passed auth");
            return getColumns(auth, name, category).then(function(){
                console.log("get columns");
                return updateSheet(auth,name,category,event).then(function(){
                    console.log("finished updating");
                    return resp.say("Successfully logged for " + name + " a " + category + " of " + event).send();
                });
            }).catch(function(err){
                console.log("failed columns");
                return resp.say(err).send();
            });
        })
        .catch(function (err) {
            console.log("Auth err: ", err);
            return resp.say("There was an error authenticating. Please check your Alexa app for how to reconnect your google account.").send();
        });
};

我的本地终端输出：

对请求使用完全相同的JSON的AWS输出：

我的节点版本都是6.10，而且我的alexa- app -server/我的app都使用alexa-app："^4.0.0“

本地响应：

{
  "version": "1.0",
  "response": {
    "directives": [],
    "shouldEndSession": true,
    "outputSpeech": {
      "type": "SSML",
      "ssml": "<speak>Successfully logged</speak>"
    }
  },
  "sessionAttributes": {},
  "dummy": "text"
}

Lambda为空：

{
  "version": "1.0",
  "response": {
    "directives": [],
    "shouldEndSession": true
  },
  "sessionAttributes": {}
}

因此，在PSU一个很棒的朋友的帮助下，我找到了答案。

我实际上是在返回我的代码，当Lambda看到返回时，它会终止函数。当在本地机器上运行时，它将返回，但不会终止进程，因此其余代码仍将运行。

为了解决这个问题，我把所有东西都包装在一个promise中，然后用一个.then()

// Did they provide all the necessary info?
    if(sampleHelper.completed()){
        // Handles reading out the menu, etc
        return sampleHelper.updateSheet(response).then(function(data){
            return response.say("Successfully logged for " + sampleHelper.getName() + " a " + sampleHelper.getCategory() + " of " + sampleHelper.getEvent()).send();
        }).catch(function(err){
            console.log(err);
            return response.say("error").send();
        });
    } 

和updateSheet：

return new Promise(function(resolve, reject) {
        authorize(JSON.stringify(access_token))
            .then(function (auth) {
                console.log("passed auth");
                getColumns(auth, name, category).then(function () {
                    console.log("get columns");
                    updateSheet(auth, name, category, event).then(function () {
                        console.log(new Date().getTime());
                        resolve("worked");
                    });
                }).catch(function (err) {
                    console.log("failed columns");
                    throw "Failed columns";
                    // return resp.say(err).send();
                });
            })
            .catch(function (err) {
                throw err;
                console.log("Auth err: ", err);
                return resp.say("There was an error authenticating. Please check your Alexa app for how to reconnect your google account.").send();
            });
    });
