SoundCloudBackend backend caused an exception

[robotrono]

I get this error when trying add this url playlist:

https://soundcloud.com/zeb-23/sets

ERROR    SoundCloudBackend backend caused an exception.

I'm reopening this, as Mopidy-Soundcloud should handle these exceptions better. No input should make it crash.

I've experiencing a similar issue but it happens with every option except Explore and Stream (I can't test Groups and Sets because I don't have does on my account).

The output:

ERROR    SoundCloudBackend backend caused an exception.

Can confirm, also for me only Explore and Stream work.

Looked into Likes specifically:

Apparently the reason is that parse_track in soundcloud.py returns either a proper Track or an empty list, for instance when the track is not streamable. We could use get_track but this returns None only when there was an exception, so without one it would just return the empty list.

Not knowing what the reason for the empty list is, I’d just wrap this part of list_liked in library.py

vfs_list[data.name] = models.Ref.track(
    uri=data.uri, name=data.name
)

in a try/except.

But imo it would be better to make the output of parse_track either None or Track to reduce a) surprises and b) amount of cases to handle after calling it.

It should be noted that PR #69 only fixes the second of two unrelated issues in this bug. The first and stack trace listed here seems totally unrelated.

Hi,

I have the same error when I start the daemon:

I can mention that I have an Arch linux, I have just upgrade the system to the latest and the python pip to the latest one

Please look into this ­– I have an issue similar to prayerslayer, except only Stream is able to load a playlist, and even then, none of the songs can be played.

Trying to enter Explore:

Entering Groups or Sets produces no output or errors (it may very well not have anything to load and actually be working properly)

Additionally, here's the error when I try to play something from Stream (in this case, Light Reading, from NMSNL):
