Error message when opening a .nix file then a .lua file

[Eddio0141]

The error I get is method textDocument/codeLens is not supported by any of the servers registered for the current buffer. This error pops up on anything I do, writing, escaping to normal mode, etc.

How to do:

1. Open some nix file
2. Open some lua file in the same session (you can use :e whatever.lua or :Explore, doesn't matter)
3. Try do anything in the lua file, :w can cause the error

• Contents of the lua file and nix file doesn't matter, they can be empty
• This doesn't happen when only having lua files opened in the session

Hey 👋

I haven't encountered this with the default setup. Is this with nixd instead of nil?

It sounds like the nixd client (which I guess supports code lenses) is somehow attaching to the Lua buffer, which leads to this autocommand being created.

Hiya This is with the default template unmodified, I directly run nix run "github:nix-community/kickstart-nix.nvim" to open some nix file, and then a lua file which causes the error for me

A short clip here goes through exactly what I'm doing

I am facing the same issue when running the flake with nix run "github:nix-community/kickstart-nix.nvim" open nix/neovim-overlay.nix :e ../kickstart-nix.nvim/nvim/lua/user/lsp.lua delete a line of code make the code look like this for example:

---@mod user.lsp
---@brief [[
---LSP related functions
---@brief ]]

---Gets a 'ClientCapabilities' object, describing the LSP client capabilities
---Extends the object with capabilities provided by plugins.
---@return lsp.ClientCapabilities
  local capabilities = vim.lsp.protocol.make_client_capabilities()
  -- Add com_nvim_lsp capabilities
  local cmp_lsp = require('cmp_nvim_lsp')
  local cmp_lsp_capabilities = cmp_lsp.default_capabilities()
  capabilities = vim.tbl_deep_extend('keep', capabilities, cmp_lsp_capabilities)
  -- Add any additional plugin capabilities here.
  -- Make sure to follow the instructions provided in the plugin's docs.
  return capabilities
end

return M

:thinking: just pulled the latest changes and can reproduce. ~It looks like lua-language-server is erroneously reporting that it supports code lenses to the client.~
