vim-smoothie and nvim-treesitter-context have conflict

[Freed-Wu]

Description

Install two plugins:
https://github.com/psliwka/vim-smoothie and https://github.com/nvim-treesitter/nvim-treesitter-context
then edit a lua file, such as https://github.com/nvim-treesitter/nvim-treesitter-context 's lua/treesitter-context/context.lua , press any hotkey of vim-smoothie, such as <C-D> (for me, 2 times), an error:

Error detected while processing CursorMoved Autocommands for "*":

OS: Arch Linux
NVIM v0.11.0
Build type: RelWithDebInfo
LuaJIT 2.1.1736781742
Run "nvim -V1 -v" for more info
vim-smoothie is git version
nvim-treesitter-context is luarocks' latest version

I tend to think this is due to vim-smoothie do some weird thing during CursorMoved ? Maybe @psliwka know.

Neovim version

0.11.0

}

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
