[SOLVED] Streaming video in an Apple TV TVJS app works in the simulator but fails on the device with an arcane error

Streaming video in an Apple TV TVJS app works in the simulator but fails on the device with an arcane error

I am trying to stream video in a TVML app. Streaming the video works in the simulator, but on the device I get an arcane error message that doesn't explain anything.

I'm using the code from this example with the below code changed in the function startPlayback(event) section.

var player = new Player();

player.playlist = new Playlist();

var video = new MediaItem('video', 'http://cdnapi.kaltura.com/p/1626222/sp/162622200/playManifest/entryId/0_eq9i2jbt/format/url/protocol/http/a.m3u8');
video.title = 'title';
video.subtitle = 'subtitle';
video.description = 'description';
video.artworkImageURL = 'artworkImageURL';

player.playlist.push(video);

setPlaybackEventListeners(player);

player.play();

Error Message:

Solution

Ugh, it was an AppTransport issue. We're whitelisting our Kaltura domains, but I guess we're missing one. When I disable AppTransport completely, the app worked without error. I wish Apple would display the domain that's not whitelisted or https when the error occurs.
