bug: Getting error on LspAttach

[farzadmf]

Did you check docs and existing issues?

• I have read all the plugin docs

• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

0.11.15

Operating system/version

MacOS 15.7.2

Describe the bug

I'm using [a heavily customized] LazyVim for Rust, and I basically copy pasted the config from README:

  {
    'alexpasmantier/krust.nvim',
    ft = 'rust',
    opts = {
      keymap = '<leader>ck', -- Set a keymap for Rust buffers (default: false)
      float_win = {
        border = 'rounded', -- Border style: "none", "single", "double", "rounded", "solid", "shadow"
        auto_focus = false, -- Auto-focus float (default: false)
      },
    },
  }

And when I open a Rust file, I get this error:

Error detected while processing LspAttach Autocommands for "*":
Error executing lua callback: ...farzadmf/.local/share/nvim/lazy/krust.nvim/lua/krust.lua:34: attempt to index field 'cmd' (a function value)

	.../neovim/0.11.5/share/nvim/runtime/lua/vim/lsp/client.lua:575: in function ''
	vim/_editor.lua: in function <vim/_editor.lua:0>

Steps To Reproduce

Nothing much to add here, basically:

1. Open a Rust file

Expected Behavior

The plugin seems to be working fine (I think) despite the error, so it would be nice not to get it in the first place (eg, silence the error) ... or better yet, fix it so that it doesn't happen 🙂

Hi, thanks for the report.

Would you mind checking out #3 and see if that solves your issue?

Thanks

PS: you'll need to point to the local copy of the repository after cloning it:

return {
  {
    dir = "~/path/to/where/you/cloned/krust.nvim/",  -- <--------------- here
    ft = "rust",
    opts = {
      keymap = "<leader>k", -- Set a keymap for Rust buffers (default: false)
      float_win = {
        border = "rounded", -- Border style: "none", "single", "double", "rounded", "solid", "shadow"
        auto_focus = true, -- Auto-focus float (default: false)
      },
    },
  },
}

Hey @alexpasmantier ; thank you for your reply

I just checked out branch = 'error-lsp-attach', and I don't get the error anymore!

[alexpasmantier]

Great, thanks for trying that out!
Closing this issue then 🎉

Great, thank you for taking care of this; I love how this shows the error; it helps me a lot personally.

I saw on Reddit that some people were a bit on the mean side, but thank you for the plugin; it is very useful for me
