The ‘gitsigns’ plugin outputs an error E5560 in neovim

Question

I am new to neovim. After I learned to install neovim and lazyvim, gitsigns plugin reported an error every time I opened a file in a project.

The error is as follows

> Error executing luv callback:
...m-data/lazy/gitsigns.nvim/lua/gitsigns/system/compat.lua:199: E5560: Vimscript function must not be called in a lua loop callback
stack traceback:

I don't quite understand why the error occurs. I need an explanation and solution for it.

Answer:

This error is a known bug in gitsigns.nvim when run on older Neovim versions (it was calling Vim-script APIs from a Lua callback). The fix landed in Neovim v0.11.1.

https://github.com/lewis6991/gitsigns.nvim/issues/1307

Solution: upgrade Neovim to v0.11.1 or later.
