response to Audioplayer.Playbackfinished / no new directive allowed

Me and my podcast skill again...

Let's say, the user asks my skill to play episodes about astronomy. My skill fetches those podcast episodes and plays the first.

Alexa tells him: "I will now play episode XYZ from ABC". Great.

User doesn't like that episode and tells Alexa to go to the next episode: "Alexa, next".

My skill fetches the next episode in the playlist it created and Alexa says: "I now play episode ABC from XYZ". Fine, all ok.

Now the user likes the episode and it plays until the end. An AudioPlayer.PlaybackFinished comes along and well, I thought I could handle both cases (NextIntent and AP.PlaybackFinished) with the same code.

But: no! I'm not allowed to include an outputSpeech or card inside the response for the PlaybackFinished. I understand, where that comes from: Music-Playlists (say an album) have ONE cover (card) and Alexa needs only once to tell, which album it plays.

But in my case it's a mixed playlist from podcasts. I'd like to tell the user, what will be played and also I like to include a card with the podcasts logo.

Dear Amazon Developer Team: Please think outside your musicbox. There's more than music :)

But now my real problem: After removing card and outputSpeech I get that error:

[message] => The skill's response must not contain more than 0 AudioPlayer.Play directive(s) for this request type

Ok, now I am confused. I want to play along with the next episode (which works fine for the NextIntent), but I cannot include an Audioplayer.Play directive to continue with the next one?

Here's my response in full:

{
  "response": {
    "card": null, 
    "directives": [
      {
        "audioItem": {
          "stream": {
            "offsetInMilliseconds": 0, 
            "token": "episode-1314328-d10c8b49ca6bcba859e80f1747f48272", 
            "url": "https://<removed>"
          }
        }, 
        "playBehavior": "REPLACE_ALL", 
        "type": "AudioPlayer.Play"
      }
    ], 
    "outputSpeech": null, 
    "reprompt": null, 
    "shouldEndSession": true
  }, 
  "sessionAttributes": {
    "episode": {
      "url": "https://<removed>"
    }
  }, 
  "version": "1.0"
}

Help!

@eazy I think PlaybackNearlyFinished is okay. I use that event to enqueue the next song.

On Playback finished I remove the previous from my internal list, so it works great.

I am Taiwanese,so English isn't nice.sorry.

you can try it.

Yor can look here.

https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-interface-reference#standard-response-to-launchrequest-or-intentrequest-example

it say:

This response does not use any interfaces (such asAudioPlayer), so it returns the standard response properties (outputSpeech,card,reprompt, andshouldEndSession)

but I am using on AudioPlayer.PlaybackNearlyFinished station.

{
    "version": "1.0",
    "response": {
        "directives": [
            {
                "type": "AudioPlayer.Play",
                "playBehavior": "REPLACE_ENQUEUED",
                "audioItem": {
                    "stream": {
                        "token": "YOUR_TOKEN",
                        "url": "YOUR_URL",
                        "offsetInMilliseconds": 0
                    }
                }
            }
        ]
    }
}

Ok, this is documented. Also documented now is, that I'm not able to read the documentation ;)

But: PlaybackFinished is a state request, you get once. PlaybackNearlyFinished can occur more than once. You start an audio, 2 minutes duration. After PlaybackStarted, you also get a PlaybackNearlyFinished. Then you pause the audio, start it again an get another PlaybackNearlyFinished... That's confusing.

It would help to be able to ignore NearlyFinished and use Finished for enqueueing.

Thank you for the insightful comments. I believe you should post them in Alexa Feature Request space.
