Started to fail after routine nix flake update

[snglth]

I ran nix flake update recently which fetched following inputs among others:

• Updated input 'nixos-unified':
    'github:srid/nixos-unified/ed937a03c0949742ff7dcd871957d80596e9f59a' (2024-10-05)
  → 'github:srid/nixos-unified/4c9a3c503952b256d6989bbfcd3a443b7eb13647' (2024-10-07)
• Updated input 'nixpkgs':
    'github:nixos/nixpkgs/27e30d177e57d912d614c88c622dcfdb2e6e6515'
  → 'github:nixos/nixpkgs/5633bcff0c6162b9e4b5f1264264611e950c8ec7' (2024-10-09)

Now every build results in following error:

<- nix run --show-trace                                                                                                                                                      nixos-config-shell-env

[srid]

Looks like it gets triggered from https://github.com/srid/nixos-unified/blob/master/nix/modules/flake-parts/autowire.nix

Can you share something about your config? Or is this reproducible in this repo as well (I haven't tested)?

[srid]

Ah, I can reproduce it:

#84

[srid]

Should be fixed in #85

[snglth]

It worked for me. Thank you.
