It seems like the tool is having trouble checking for already existing files (corrupted .m4a downloads? idk). Could you try downloading tracks to a different directory with debug logging enabled? If these errors still occur, post the output here. I'll see if I can narrow down the problem.

I am having these errors. I have tried both the ways to download tracks.

[volgar1x]

I'm having the same issue as of spotdl 1.2.0

[ritiek]

I've released v1.2.1. See https://github.com/ritiek/spotify-downloader/issues/149#issuecomment-487371795 on how to update. Does updating to v1.2.1 fix the problem?

[crash-override404]

Update v1.2.1 i got error in pafy, i'm already update the pafy but still error

Edit : Solved by updating youtube-dl Thanks

[maltejur]

For me the problem is solved with v1.2.1.

[ritiek]

Thanks for the heads up! I'll close this as fixed.

[GipsyBeggar]

Update v1.2.1 i got error in pafy, i'm already update the pafy but still error

Edit : Solved by updating youtube-dl Thanks
Same here:
pip install --upgrade youtube-dl
