attempt to index local 'node' (a nil value)

[gennaro-tedesco]

Good afternoon and thank you for always producing great plugins!

I am running

nvim --version
NVIM v0.9.0-dev-1290+g2257ade3d-dirty

and have installed the plugin via lazy.nvim (not that it matters); while attaching it to the language servers as per README (or alternatively by specifying

lsp = {
        auto_attach = true, 
    }

I get the exception (upon invocation of :Navbuddy)

Error executing vim.schedule lua callback: ...re/nvim/lazy/nvim-navbuddy/lua/nvim-navbuddy/display.lua:75: attempt to index local 'node' (a nil value)

Subsequently also

Error detected while processing CursorMoved Autocommands for "<buffer=87>":

(or any other buffer number).

The line in question is this one and the method in question is node.parent.

I notice there is a reference to HEAD-2257ade in the stack trace, latest commit on nightly, may that be the cause?

Yeah that looks suspicious 🤔 . Also I noticed dirty added on to your version number, what does that mean? Mine is just showing NVIM v0.9.0-dev-1290+g2257ade3dc

Could you share some minimal C++, python or even lua file where you are able to recreate this issue? I am not able to reproduce it 😓 Also just a hunch, could you try wrapping this line in if not equal to nil check. Let me know if it helps.

I seem to be getting the same error in a Python file on Nvim 0.8.3 (with jedi language server). Haven't had the time to look at it more in-depth, though.

I've got the same error in Nvim Nightly from today with Typescript language server

[SmiteshP]

Tried typescript server. got the error 👍🏽 So my guess is that it is lsp server specific issue. Looking into it

[SmiteshP]

Fixed the issue from nvim-navic side. Can you guys update to latest nvim-navic and let me know if the issue if fixed?

[yngwi]

I don't get the error any more! Thank you!

[sf8193]

that fixed it for me as well! thanks, very promising plugin

[gennaro-tedesco]

Updating fixes the error for me as well. As far as I am concern, we can close this issue as solved!

[ColonelPhantom]

Seems to work here too!

[SmiteshP]

Closing issue as problem is solved 🥳
