LSP Error: _changetracking.lua:305: attempt to index local 'buf_state'

[gepbird]

Problem

This error comes up on every change to the buffer when it is in a "broken state". Doing :e fixes this issue.

Error executing lua callback: ....10.0/share/nvim/runtime/lua/vim/lsp/_changetracking.lua:305: attempt to index local 'buf_state' (a nil value)

Steps to reproduce

Most likely after doing file operations with git (fugitive), opening a previously opened file will put the buffer in a "broken state". At least this is what seems to cause it, I'll try to make it consistently reproducible later.

Expected behavior

No error

Neovim version (nvim -v)

NVIM v0.10.0

Vim (not Nvim) behaves the same?

Most likely not

Operating system/version

NixOS

Terminal name/version

xfce4-terminal

$TERM environment variable

xterm-256color

Installation

nixpkgs/nixos-unstable

This is fixed on master. Commit: 2908f71

[gepbird]

@icholy Thanks! I'll try it.

[icholy]

FYI @mfussenegger your refactor had some type of behaviour change which fixed this 2908f71 so it should be backported

[dylan-chong]

is this fix going to be released any time soon?

[icholy]

@dylan-chong the fix will be included in 0.10.1 here's the milestone https://github.com/neovim/neovim/milestones/0.10.1

[caarlos0]

any workarounds besides using nightly?

any workarounds besides using nightly?

@caarlos0 0.10.1 just dropped for me in homebrew, but I haven't been able to confirm if the issue persists.

[chrisgrieser]

I am on 0.10.1 and the issue still occurs for me. It occurs only in gitcommit files (COMMIT_EDITMSG), where the typos-lsp is attached.

[icholy]

@chrisgrieser can you reproduce this consistently?
