error : .../lib/attresets.nix is not in ...-source

When trying to update a package in a flake I encountered the following error:

I'm not sure exactly what is the problem...

The derivation file is the following:

{
  appimageTools,
  lib,
  fetchurl,
}:
appimageTools.wrapType2 rec {
  pname = "warcraftlogs";
  version = "6.0.2";

  src = fetchurl {
    url = "https://github.com/RPGLogs/Uploaders-warcraftlogs/releases/download/v${version}/Warcraft-Logs-Uploader-${version}.AppImage";
    hash = "sha256-b1Lt8ssL+Isd/Twv6ef3AK4/BkxWA/TtleameONo/2Q=";
  };

  extraInstallCommands = let
    appimageContents = appimageTools.extractType2 {inherit pname version src;};
  in ''
    install -m 444 -D ${appimageContents}/${pname}.desktop $out/share/applications/${pname}.desktop
    substituteInPlace $out/share/applications/${pname}.desktop --replace 'Exec=AppRun' 'Exec=${pname}-${version}'
    install -m 444 -D ${appimageContents}/usr/share/icons/hicolor/256x256/apps/${pname}.png \

  '';

  meta = with lib; {
    homepage = "https://www.warcraftlogs.com/";
    description = "Tool to upload world of warcraft combat logs";

    maintainers = with maintainers; [traxys];
  };
}

Looks like one flake tries to access another flake with an absolute import path?

error: /nix/store/p69bcs7ma6ijj8v9xsrg3nq3nn8ryn95-source/lib/attrsets.nix is not in /nix/store/l3hss47a3wqkx275p5by3kyhhc620nly-source

Can you check out what /nix/store/l3hss47a3wqkx275p5by3kyhhc620nly-source and /nix/store/p69bcs7ma6ijj8v9xsrg3nq3nn8ryn95-source/lib/attrsets.nix is? The first might be NUR and the other one might be nixpkgs?

I think it has something to do with:

warning: input 'nur' has an override for a non-existent input 'nixpkgs'

I am also having this issue, this doesn't seem to have anything to do with extra flake inputs. I created a flake where the only flake input is nixpkgs. the "source" appears to be the flake.

error: /nix/store/7v6l2v247fmdgfpbs3w91mf6rinai4yk-source/lib/attrsets.nix is not in /nix/store/4kmip8a3k9n5z59wcah3jzrar7lwm3i9-source

[LovingMelody]

This issue looked to be because of the package using appimageTools:

❯ nix eval .\#gameglass.meta.position                                 
"/nix/store/7v6l2v247fmdgfpbs3w91mf6rinai4yk-source/lib/attrsets.nix:984"

So I tried a different package..

{
  lib,
  stdenv,
  fetchFromGitHub,
  nix-update-script,
  ...
}:
stdenv.mkDerivation (finalAttrs: {
  pname = "catppuccin-base16";
  version = "git+${builtins.substring 0 8 finalAttrs.src.rev}";
  src = fetchFromGitHub {
    owner = "catppuccin";
    repo = "base16";
    rev = "99aa911b29c9c7972f7e1d868b6242507efd508c";
    hash = "sha256-HHodDRrlcBVWGE3MN0i6UvUn30zY/JFEbgeUpnZG5C0=";
  };

  passthru.updateScript = nix-update-script { extraArgs = [ "--version=branch" ]; };

  meta = {
    description = "Base16 Catppuccin theme";
    homepage = "https://github.com/catppuccin/base16";
    platforms = lib.platforms.all;
    license = lib.licenses.mit;
  };

  installPhase = ''
    mkdir -p $out/share
    cp -r $src/base16 $out/share/themes
  '';
})

This gives me a similar but different error:

error: /nix/store/mr50vwmkskid925jf21fg3w4n43jq558-l393p8dfvmbmydcjmc8iqqsd101b3fns-source/packages/catppuccin-base16/default.nix is not in /nix/store/l393p8dfvmbmydcjmc8iqqsd101b3fns-source

But the path does exist:
