I'm not getting completin candidates from nixd

[shackra]

I'm trying to get auto-completion in nix-mode but is impossible. show-log.log

I added a client:

(after! lsp-mode
  (lsp-register-client
   (make-lsp-client :new-connection (lsp-stdio-connection "nixd")
                    :major-modes '(nix-mode)
                    :priority 1
                    :server-id 'nixd)))

Added the minimum amount of server configuration to my flake.nix:

{ inputs, ... }:
{
  # NixOS configuration.
  nix.nixPath = [ "nixpkgs=${inputs.nixpkgs}" ];
}

but I get no completion candidates still.

I'm using this version of nixd:

➜  nixd --version
nixd, version: nightly

[jcs090218]

The log looks normal to me. 🤔 A Nix client is already specified in this project. See https://github.com/emacs-lsp/lsp-mode/blob/master/clients/lsp-nix.el.

I've tried it on macOS, and it works fine. It has only a few completions, but I can get it to work.
