Current tree sitter setup for neorg?

[Anrock]

So, I have neovim 0.11.4, rocks.nvim as plugin manager with neorg 9.3.0 installed. I also have nvim-treesitter-legacy-api 0.9.2 since neorg requires it (but doesn't have it as dependency for some reason, wasn't it the whole point of rocks.nvim?) and will barf at startup without it installed. I also have rocks-treesitter.nvim and a bunch of tree-sitter-* plugins for every language I use, including neorg.

The problem is that nvim-treesitter-legacy-api seems to be broken. Or maybe neorg tree-sitter related code is broken. Or it conflicts with rocks-treesitter. Or I don't know.

The symptoms so far is that opening any .c files produces endless stream of errors like

Error in decoration provider "line" (ns=nvim.treesitter.highlighter):
Error executing lua: ...rocks/rocks_rtp/lua/nvim-treesitter/query_predicates.lua:80: attempt to call method 'parent' (a nil value)

Which appear for basically every keystroke and essentially lock up neovim.
According to google that was a bug years ago and every issue that mentions this error message is closed as resolved.

Another symptom is :checkhealth nvim-treesitter says errors found in the query, try to run :TSUpdate {lang} ~ yet :TSUpdate command is unavailable.

I kinda blame neorg here since it looks like the error is coming from this legacy-api plugin and it is a crutch for neorg but maybe my blame is misplaced.

So, what is the proper way to have neorg without breaking tree-sitter for other languages?
