I'm trying to build an Alexa skill that can play an audio file. I'm trying to send an Audio Player Play directive in the Launch Request, but when I use this code, I get no response back from my Alexa. Does it look correct?

const LaunchRequestHandler = {

  canHandle(handlerInput) {

    return handlerInput.requestEnvelope.request.type === 'LaunchRequest';

  },

  handle(handlerInput) {

    console.log('IN LAUNCHREQUEST');

    return handlerInput.responseBuilder

        .addDirective({

            type: 'AudioPlayer.Play',

            playBehavior: 'REPLACE_ALL',

            audioItem: {

                stream: {

                    token: "0",

                    url: "myurlhere",

                    offsetInMilliseconds: 0

                }

            }

        })

    }

};

You must return a "built" response, in the handler. So in you case the code would be:

const LaunchRequestHandler = {

  canHandle(handlerInput) {

    return handlerInput.requestEnvelope.request.type === 'LaunchRequest';

  },

  handle(handlerInput) {

    console.log('IN LAUNCHREQUEST');

    return handlerInput.responseBuilder

        .addDirective({

            type: 'AudioPlayer.Play',

            playBehavior: 'REPLACE_ALL',

            audioItem: {

                stream: {

                    token: "0",

                    url: "myurlhere",

                    offsetInMilliseconds: 0

                }

            }

        })

        .getResponse();

        // ^^^ add this line

    }

};

If you are using alexa sdk v2 (https://github.com/alexa/alexa-skills-kit-sdk-for-nodejs) then you can use inbuilt methods to play audio. Following methods are available to play long form audio.

addAudioPlayerPlayDirective(playBehavior: interfaces.audioplayer.PlayBehavior, url: string, token: string, offsetInMilliseconds: number, expectedPreviousToken?: string, audioItemMetadata? : AudioItemMetadata): this;

addAudioPlayerStopDirective(): this;

addAudioPlayerClearQueueDirective(clearBehavior: interfaces.audioplayer.ClearBehavior): this;

More information can be found on https://ask-sdk-for-nodejs.readthedocs.io/en/latest/Building-Response.html

Following is a code snippet that I use in my lambda to play audio.

//Create Image to be displayed with song



const metadata = {

    title: 'Stopwatch Audio',

    art: {

        sources: [{

            url: imageUrl

        }]

    }

};

handlerInput.responseBuilder.speak(speechText).addAudioPlayerPlayDirective("REPLACE_ALL", audiofile, audiofile, 0, null, metadata).withShouldEndSession(true).getResponse();
