Sergei Zimmerman (xokdvium): https://github.com/NixOS/nix/pull/14696#issuecomment-3619665616 not sure yet if it's related to this change, but I just got an error that it couldn't find a "uid" in my dotfiles for hercules-ci-effects, unfortunally I didn't copy the error and now it no longer reproduces.

hercules-ci-effects.url = "github:hercules-ci/hercules-ci-effects";
