Describe the Bug

When try to open the neo-tree sidebar getting this error and I cannot load the neo-tree buffer.

It says [Neo-tree ERROR] Error setting nodes: .../.local/share/nvim/lazy/nui.nvim/lua/nui/tree/init.lua:36: duplicate node id/Users/<project_path>/.flake8

Mostly it has issues with .flake8 file.

Steps to Reproduce

1. Just open neovim and try to open the neo-tree buffer

Expected Behavior

1. Should show my files

Your Configuration

I'm getting a similar error with .python-version.

[Neo-tree ERROR] Error setting nodes: ...er/.local/share/nvim/lazy/nui.nvim/lua/nui/tree/init.lua:36: duplicate node id/home/<user>/<project_path>/.python-version

Neovim Version (nvim -v)

Build type: RelWithDebInfo

Operating System / Version

Arch Linux

EDIT

Adding it to filesystem.filtered_items.never_show works. I'm ok with that, as there is rarely a reason to edit it by hand anyway.

filesystem = {
  filtered_items = {
    visible = true,
    never_show = { '.git', '__pycache__', '.python-version' },
  },
...
