context.lua:17: attempt to index local 'tree' (a nil value)

[benjyiw]

Description

I ran an upgrade of all my plugins earlier today. Now I'm having trouble working with some files that are incorrectly formatted. I'm getting constant errors when attempting navigation. Copied the trace into the "actual behavior" section.

My solution for now was to go back to the commit prior to recent changes to context.lua around like 17, where the stack trace starts, and all is well. Figured I would open an issue since others may also be experiencing the same

Neovim version

NVIM v0.9.5

Expected behavior

No response

Actual behavior

Error detected while processing CursorMoved Autocommands for "*":

Minimal config

local plugins = {
  ts         = 'https://github.com/nvim-treesitter/nvim-treesitter',
  ts_context = 'https://github.com/nvim-treesitter/nvim-treesitter-context',
  -- ADD ADDITIONAL PLUGINS THAT ARE _NECESSARY_ TO REPRODUCE THE ISSUE
}

for name, url in pairs(plugins) do
  local install_path = '/tmp/nvim/site/'..name
  if vim.fn.isdirectory(install_path) == 0 then
    vim.fn.system { 'git', 'clone', '--depth=1', url, install_path }
  end
  vim.o.runtimepath = install_path..','..vim.o.runtimepath
end

-- ADD INIT.LUA SETTINGS THAT IS _NECESSARY_ FOR REPRODUCING THE ISSUE
require'nvim-treesitter.configs'.setup {
  ensure_installed = { "yaml" },
}

Steps to reproduce

1. Open some file with bad formatting with neovim nvim --clean -u minimal.lua bad.yaml

here's a bad yaml example:

key1:
    key2: value
  badkey: value

2. Attempt navigation around "badkey" and stack traces should go crazy.

I'm facing the same issue. Which commit did you go back to @benjyiw ?

[kwaszczuk]

I am looking into the issue.

@ShellCode33 It was most likely caused by 0a95d47 so going back to 32bbb21 should help.
