Getting error (attempt to index field 'data' (a nil value)) if auto_attach is set to true

[thatanjan]

I installed this plugin with the following code.

    use {
        "SmiteshP/nvim-navbuddy",
        requires = {
            "neovim/nvim-lspconfig",
            "SmiteshP/nvim-navic",
            "MunifTanjim/nui.nvim",
            "numToStr/Comment.nvim", -- Optional
            "nvim-telescope/telescope.nvim", -- Optional
        },
        config = function()
            require("nvim-navbuddy").setup {
                lsp = {
                    auto_attach = true, -- If set to true, you don't need to manually use attach function
                },
            }
        end,
    }

I am getting this error when I open a file. But the plugin just works fine after that.

Can you check if this occurs in current neovim stable release as well for you? If not this could be some bug in the nightly version.

[thatanjan]

@SmiteshP I have tried the stable version but getting the same problem

[SmiteshP]

@thatanjan @navxio Is this occuring for any specific language? I am not able to reproduce this issue 🤔

[navxio]

@SmiteshP Apparently it happens with both lua and python for me.. I'm using neodev / lspconfig.pyright if that helps..

Here's the whole thing: https://github.com/navxio/dots/blob/trunk/.config/nvim/init.lua

[thatanjan]

@thatanjan @navxio Is this occuring for any specific language? I am not able to reproduce this issue thinking

@SmiteshP I have tried on ts, tsx, less, py. Basically, it occurs on all filetypes if you have lsp server installed for that file.

[SmiteshP]

@thatanjan @navxio Can you guys checkout the debug branch, have auto_attach=true in config and then open any file that shows this issue. Then run :messages command and paste the output here?

And for now as a work around you may use manual attachments instead

[thatanjan]

@SmiteshP here is the output.

Aah I see whats happening!

The first autocommand being triggered is correct

{                                                                                                                                                                           
  buf = 1,

    client_id = 1                                                                                                                                                           
  },                                                                                                                                                                        
  event = "LspAttach",                                                                                                                                                      
  file = "/home/anjan/.dotfiles/.config/qtile/config.py",                                                                                                                   
  id = 80,                                                                                                                                                                  
  match = "/home/anjan/.dotfiles/.config/qtile/config.py"                                                                                                                   
}          

But something is triggering the second autocommand as well which doesn't contain the data for some reason. Cannot definitively say whats causing this since I cannot reproduce the error, but perhaps some plugins you both have in common is doing it? Anyways, I can add a small check to ensure that data field is not null to fix the issue.

Latest commit should have fixed this issue for you guys

[thatanjan]

I still have the problem.

Did you switch to master branch again?

Did you switch to master branch again?

Yes.

[SmiteshP]

Huh weird.. The if else check I added should prevent this error 🤔 Can you paste the error message again? is it the same error? Also can you double check if you are on latest commit of master.

[thatanjan]

Yes, I am using the master branch with the latest commit. Here is the error

Just found out that the problem was with the Lspsaga plugin with Packer. Check this issue. https://github.com/nvimdev/lspsaga.nvim/issues/1128
