Description

Error 1: Keymaps not working

When we are in a Rust piece of code, let's say here:

If I do the keymap action, it doesn't work (and isn't even registered as an option in which-key menu).
However, if I call manually, like: lua vim.lsp.buf.code_action(), it works!
This is true for every lsp action, like open_float diagnostics, go to references, defnition, etc.

Also, this isn't only for Rust (which I setup with Rustaceanvim), but the same behaviour happens in Nix.

Error 2: Lsp getting into some sort of mixup with autocommands

ordinal = '  Error 13:25:34 Error detected while processing LspProgress Autocommands for "*":'

Error 3: Lsp breaking Noice

Error executing lua callback: neovimPackages/start/noice.nvim/lua/noice/lsp/progress.lua:20: attempt to index local 'result' (a nil value)

Minimal, Reproducible Example (MRE)

programs.nixvim = {
  plugins.lsp = {
    enable = true;
    servers = {
      # in my case I enabled rustaceanvim, but you could enable rust-analyzer here, as well
      nil_ls = {
        enable = true;
        settings.formatting.command = [ "nixpkgs-fmt" ];
      };
    };
  
    keymaps = {
      diagnostic = {
        "[d" = {
          action = "goto_prev";
          desc = "Go to prev diagnostic";
        };
        "]d" = {
          action = "goto_next";
          desc = "Go to next diagnostic";
        };
        "<leader>ld" = {
          action = "open_float";
          desc = "Show Line Diagnostics";
        };
      };
  
      lspBuf = {
        "<leader>ca" = {
          action = "code_action";
          desc = "Code Actions";
        };
        "<leader>rn" = {
          action = "rename";
          desc = "Rename Symbol";
        };
        "<leader>f" = {
          action = "format";
          desc = "Format";
        };
        "gd" = {
          action = "definition";
          desc = "Goto definition (assignment)";
        };
        "gD" = {
          action = "declaration";
          desc = "Goto declaration (first occurrence)";
        };
        "gy" = {
          action = "type_definition";
          desc = "Goto Type Defition";
        };
        "gi" = {
          action = "implementation";
          desc = "Goto Implementation";
        };
        "<leader>K" = {
          action = "hover";
          desc = "Hover";
        };
        "<leader>sh" = {
          action = "signature_help";
          desc = "Signature Help";
        };
        "<leader>gr" = {
          action = "references";
          desc = "References to thing";
        };
        "<leader>vws" = {
          action = "workspace_symbol";
          desc = "Workspace symbol";
        };
      };
    };
  };
};

I found the fix commit:
neovim/neovim@e14e750

I just don't understand why it doesn't already work for me, since nixvim unstable is at neovim/neovim@e3ec974.

i'm unable to reproduce with the provided example (i tried both nix and rust). ensure that nixvim is updated. if using flakes that would be nix flake lock --update-input nixvim
