WARNING:Librespot:CdnManager:Couldn't extract expiration, invalid parameter in CDN

Windows 11 Docker Desktop (WSL2)

I'm launching Spodcast using a custom wrapper. This has worked flawlessly for 12+ months I'd say...

It's hard to put an exact timeframe on it, but my last successful download was ~27th December. Since then, I've been getting issues like this;

I've gone back through the readme and effectively performed clean installs, re-adding credentials etc, to very little avail.

The example in the readme does /occasionally/ work... docker run -it -v c:\ProgramData\spodcast:/data heywoodlh/spodcast -c /data/spodcast.json --log-level info --max-episodes 1 'https://open.spotify.com/show/4rOoJ6Egrf8K2IrywzwOMk'

...so I'm unsure what's causing the more often than not, errors.... issues with the episode/filenames perhaps?

Occasionally getting --

ValueError: invalid literal for int() with base 10: 'Expires=1704662961~FullPath~hmac=-dWE2nKEJkT-kblZMV24Fc'

[denniskrol]

Pretty sure that's this issue: https://github.com/librespot-org/librespot/pull/1183 That should be fixed in librespot, but I don't know why that isn't updated in Spodcast yet. I just run the command a couple of times, when you get domains with the 'old' expiration format it works.

Things have not been updated in Spodcast because I'm busy with other things. I'll try to give this some time (trying right now but the spotty mobile network in this German train is not helping...) to see if I can get it back on track.
