builds fine, I think you can adapt it back without too much issue.

Hey everyone, I was trying to package up aw-watcher-mpd using poetry2nix, but I am running into the following issue. Can someone give me a hint as to where to look or what could be wrong? You can find the derivation here ref. The failing CI run can be found here.
