Error: Parser could not be created (treesitter highlight)

[0xJWLabs]

I got this error

vim.schedule lua callback: ...s/nvim-linux64/share/nvim/runtime/lua/vim/treesitter.lua:116: Parser could not be created for buffer 14 and language "typescriptreact"

Since I’m on mobile, I can’t do PR. but the culprit is there

blink.cmp/lua/blink/cmp/utils.lua

Line 85 in cfaf9fc

local trees = vim.treesitter.get_parser(bufnr, root_lang)

my current solution right now is to make root_lang = "tsx" if root_lang == "typescriptreact"

@Saghen I am getting a variant of this crash:

Error executing vim.schedule lua callback: ...ik/.nvim/share/nvim/runtime/lua/vim/treesitter/_fold.lua:72: Parser could not be created for buffer 11 and language "blink-cmp-signature"
stack traceback:

Repro steps:

1. Set up tree-sitter folding: https://github.com/fredrikaverpil/dotfiles/blob/e1724d3493df4713082c9cc03bf7d3f9f192bafa/nvim-fredrik/lua/fredrik/config/options.lua#L92-L93
2. In Lua, use snippet: https://github.com/fredrikaverpil/dotfiles/blob/3e24f345714a606714ec9038bdb8b6d4070531ba/nvim-fredrik/snippets/lua.json#L3
3. Invoke snippet and start typing "foo (and crash is hit).

I'm on Neovim 0.11 nightly and blink.cmp v0.8.2:

NVIM v0.11.0-dev-1427+gd3951be4a0
Build type: RelWithDebInfo
LuaJIT 2.1.1734355927
Run "nvim -V1 -v" for more info

Should I file a formal bug report in the issue tracker?
