Error when opening a Nix file

[RaitoBezarius]

With the recent nixpkgs bump of nil, I'm getting:

LSP[nil_ls] Failed to evaluate NixOS options: Nix eval failed with exit status: 1. Stderr:

while opening files which does not have any nixpkgs relation.

Does it ring a bell?

The error is triggered when it tries to load nixpkgs flake input. Do you have an input named nixpkgs but is not a recent enough nixpkgs?

[d4ilyrun]

Did you try running nix flake archive?

Should not be relevant. The failed Nix is at https://github.com/oxalica/nil/blob/2023-05-02/crates/nix-interop/src/nixos_options.nix which is used to dump all NixOS options for the flake input named "nixpkgs".

I personally don't use flakes so I don't really know where does this input would come from neither what is its freshness, I opened this in the NixOS/Ofborg repository (maintainers.nix).

How could I debug this further?

Oh it uses nixos-22.11. We should somehow check the revision of a dumped nixpkgs before the evaluation, but I have no clear idea.
