Cannot start systemd service, broken symbolic link

[SuperKenVery]

/home/ken/.config/systemd/user/auto-fix-vscode-server.service: broken symbolic link to /nix/store/912jjzzgnmx5zmgk5k16f7jsxjwvfmp4-unit-auto-fix-vscode-server.service/auto-fix-vscode-server.service

It's actually in /nix/store/6471nwwfn800igw70hbwvs2prq2ssy2n-unit-auto-fix-vscode-server.service/auto-fix-vscode-server.service

My configuration:

  # VSCode server auto fixup
  imports = [
    (fetchTarball "https://github.com/nix-community/nixos-vscode-server/tarball/master")
  ];
  services.vscode-server = {
    enable = true;
    enableFHS = true;
  };
