Errors and warnings with nix flake.

[TornaxO7]

Hi! I'm trying to add a home-manager module to clipcat. However, I'm already getting errors although I didn't change anything:

       error: attribute 'version' missing
       at /nix/store/0bmzw2riqpf8ikw0dvcza46lpif1lw2d-source/flake.nix:89:33:
           88|           container = pkgs.callPackage ./devshell/container.nix {
           89|             inherit (cargoToml) version;
             |                                 ^
           90|             inherit name clipcat;

The solution for this is easy, however after fixing this issue I'm getting new ones after executing nix flake check:

Are those issues known?
