treesitter error when I open doc throught telescope

[asdf8601]

When I hit <leader>sh which is mapped to telescope help_tags function, this error comes up:

Error executing vim.schedule lua callback: /usr/local/share/nvim/runtime/lua/vim/treesitter/query.lua:219: query: invalid node type at position 14 for language help

I have no idea how to deal with this and maybe I should open this issue on telescope?

[tjdevries]

make sure that you have most up-to-date neovim and associated plugins (either 0.8.1 stable release or nightly).

[asdf8601]

yes, I've checked it (PackerUpdate and I built neovim using nigthly tag)

[asdf8601]

I've done it again just to be sure (sudo cmake --build build/ --target uninstall
and sudo make install of 0.8.1 and rm -rf ~/.local/share/nvim, nvim +PackerInstall) , same error when I press <leader>sh.

Also, if no preview, no errors (it seems something related with nvim doc).

I've executed :checkhealth and here's the treesitter section in case it helps:

Thanks for the repro steps -- I will check soon (hopefully today or this weekend) and let you know what I find.

[tjdevries]

One thought I had is to put this: ensure_installed = { 'c', 'cpp', 'go', 'help', 'lua', 'python', 'rust', 'typescript' }, in for the ensure_installed (i.e. add "help" to the list) and then make sure all the tree sitters are up-to-date as well.

[asdf8601]

yes!! adding 'help' into the list fixed the issue magically! ;-)
