alexa-skills-kit-sdk-for-nodejs with external service

[amdev28]

I am able to invoke the lambda expression using Alexa sdk, but unable to call the external service from the lambda expression. I am not getting any error or response. I'm not sure what's wrong with this. While testing the lambda expression I'm only able to get the logs until 'Do the POST call', not after that. That means something wrong in https.request. The same logic tested with node.js is able to get the response correctly. Any thoughts?

var https = require('https');
    var responseString = ''; 

    var postheaders = {
        'Content-Type' : 'application/json'//,
        //'Content-Length' : Buffer.byteLength(jsonObject, 'utf8')
    };

    var optionspost = {
        host : '{host name}',
        port : 443,
        path : '{path name}',
        method : 'POST',
        headers : postheaders
    };

    console.info('Options prepared:');
    //console.info(optionspost);
    console.info('Do the POST call');

    // do the POST call
    var reqPost = https.request(optionspost, function(res) {

        console.log("statusCode: ", res.statusCode);
        // uncomment it for header details
        // console.log("headers: ", res.headers);

        res.on('data', function(d) {
            console.info('POST result:\n');
            process.stdout.write(d);
            responseString += d;
            console.info('\n\nPOST completed');
        });

        res.on('error', function(e) {
            console.error('error');
            console.error(e);
        });

        res.on('end', function () {
            console.info('end');       
            var responseObject = JSON.parse(responseString);

            if (responseObject.error) {
                console.info("NOAA error: " + responseObject.error.message);        
            } else {
                console.info(responseString);             
            }
         });
    }).on('error', function(e) {
        console.error('Communications err' + e);
        console.error(e);
    }); 

reqPost.end();
reqPost.on('error', function(e) {
    console.error(e);
}).on('error', function (e) {
        console.log("Communications error: " + e.message);        
});

Hi @amdev28

Could you post code for the handler which is executing this function. It's possible that the function is terminating prior to the HTTP call returning. It's also possible that your lambda function is timing out, have you checked the cloudwatch logs? look for a timeout exceeded error message.
