Playlist track parsing crashes, if a track is unavailable.

[exislow]

We might found a bug / new behavior of TIDAL, which is reported here: exislow/tidal-dl-ng#662

There is a public playlist, which apparently has a track, which is unavailable inside. If I get the metadata of the playlist, all is still good. But as soon as I request the tracks of the playlist, one track is returned as:

TypeError: 'NoneType' object is not subscriptable

Apparently mediaMetadata is missing and the this library crashes. Shall this be handled accordingly or is this misbehavior of TIDAL?

[tehkillerbee]

Yes, this issue is (partially) fixed and merged: #382

You can test how it works for you from latest sources. However, I think it needs to be handled slightly differently, as tracks can never be downloaded anyways when Unavailable. So they should be skipped instead IMO.

There is a public playlist,

Do you have a playlist ID? I would like to test this myself

[exislow]

There is a playlist posted in the mentioned issue in my first post (https://listen.tidal.com/playlist/93f6d95b-cdfe-4ee6-8c10-84098e265535)

Thanks for the quick reply! My app already handles unavailable media items. But it totally relies on this projects API data parsing, which caused the issue in this case. Great that it is already solved. I will verify with the latest master branch and report back.

Unfortunately this has not fixed the issue, see:

Maybe a hasattr() check would do it?

[tehkillerbee]

Looks like the returned obj isnt actually json and cannot be accessed as a dict. So we most likely need an extra check in this case. I'll take a look at your playlist and see if there is a quickfix. 👍

[tehkillerbee]

Should be fixed now in #386

[exislow]

Works great, thank you!
