Transferring playback error

[xmow49]

The problem

Hello,
Thanks for the work on spotcast v5.

Sometimes, when I use spotcast.transfer_playback I have an error (see Anything in the logs that might be useful for us?)

This error occur only rarely; do you have any information why ? and how to avoid it ?

Thanks

@xmow49 seems to be an edge case for when your last known active playback was context less (meaning you have no currently active playback and the last known playback cannot be resumed automatically). I'll check to push a fix, shouldn't be too complex.

The default in this specific case should be to play your liked songs, since their is no context to resume from.

[fcusson]

@xmow49 should be fixed in build 20

[xmow49]

Hello @fcusson
Many thanks for this quick fix.
For now, it's working, I will let you know if any other error occurs.

Thanks again and happy new year.

[fcusson]

@xmow49 glad to here it.

Happy new year to you too

Hi,

I think is also an empty playback list.
@fcusson Do you know the timeout of an active playback on Spotify?
Can it be related to a certain amount of time of non playing music?

Thanks

[fcusson]

@xmow49 that's my bad, I wrongly made the assumption that the key context was missing from the playback state but in reality, the key exist, but return null. That's a quick fix.

Can it be related to a certain amount of time of non playing music?

I'm already taking into account the expiration of the playback context, that's actually while trying to rebuild the context from the last known state that you are getting this error. Just tweaked the function a bit, should work better now. I also modified the tests to better account for the real format of a context less playback state.

[fcusson]

just pushed build 21, should be working fine now

[xmow49]

Thanks again for your responsiveness.
I'll keep you informed of any further errors.
