My Question or Issue

Hello.

I develop a web client app of Spotify using Web Playback SDK.

There seems to be duration_ms prop in WebPlaybackObject. (green underlined part of the image below)

WebPlaybackTrack object

But, in Web Playback SDK Reference, duration_ms prop isn't listed. I think the reference is missing duration_ms prop.

Hey @nokazn, thanks for letting me know about this!

I'd love to take a closer look here. Just to confirm, when you make a request, you do get the duration_ms prop? It's only the website that doesn't show this in the reference? Let me know and I'd be happy to pass that on to the right folks.

Thanks, have a good one,

Hubo

Hello, @Hubo.

I'm so sorry for the late replay.

I can recieve duration_ms prop in track objects when playback state has changed.

As far as I can see, the link above is the only reference about WebPlaybackTrack object.

Thank you.

Edit:

There is a type declaration package for TypeScript in @types/spotify-web-playback-sdk, and this also doesn't include duration_ms field in Track interface.

Additionally, the track object in the image above contains linked_from & linkd_from_uri field, but these seem to always return null at present.
