Playback not found about node-ari-client HOT 2 OPEN

I'm guessing the underlying Playback application hasnt been loaded into Asterisk. Can you go into the Asterisk console and do a core show applications and see if Playback is listed?

From the example above it doesn't look like that playback object was used to play a sound on a channel. What was done was create an object with a placeholder ID but Asterisk doesn't know about it yet. You'll need to use that object to play a sound on a channel or bridge first:

channel.play({ media: 'sound:some-sound' }, playback, function (err, updatedPlayback) {});

The goal of creating the playback object is so you have an ID ahead of time for registering events and controlling the playback.
