Nvf nixd + lsp autocompletions not happening.

[argosnothing]

(making this a QA since this is likely a me doing it wrong issue)
At my wit's end here. my nvf config should be setup correctly in my case, but I am getting nixd eval errors all over the place and it seemingly ignores any autocompletion for everything but stuff like home.packages = with pkgs; [xyz]; with or without me actually setting it under the options.

The example config ALSO does the same thing for me? So maybe im using the autocompletion wrong? but logs are saying it is actually making requests so.

Here is the critical part of the code that im trying to get to work

languages = {
        enableFormat = true;
        enableTreesitter = true;
        enableExtraDiagnostics = true;
        nix = {
          enable = true;
          treesitter = {
            enable = true;
          };
          lsp = {
            enable = true;
            server = "nixd";
            options = {
              nixpkgs = {
                expr = "import <nixpkgs> { }";
              };
              formatting = {
                command = ["alejandra"];
              };
              nixos = {
                expr = "(builtins.getFlake \"${settings.absoluteflakedir}\").nixosConfigurations.${settings.hostname}.options";
              };
              home-manager = {
                expr = "(builtins.getFlake \"${settings.absoluteflakedir}\").homeConfigurations.\"${settings.username}@${settings.hostname}\".options";
              };
            };
          };
          extraDiagnostics.enable = true;
          format = {
            enable = true;
            type = "alejandra";
          };
        };
        markdown.enable = true;
      };

It seems to only be filling in based on context?

Mainly using these links to make sure i'm even doing this right:
