Conflict with nvim-tree float window

[LinoWhy]

Opening nvim-tree in a float window then quit, leads to following error:

It seems that WinLeave autocmd of nvim-tree and nvim-lightbulb have conflicts.
Beside, can we use the ignore option in autocmd pattern?

    ignore = {
        -- Filetypes to ignore.
        -- Example: {"neo-tree", "lua"}
        ft = {},
    },

Any update on this? I am facing a similar issue.
Update: Setting "hide_in_unfocused_buffer = false", fixes the issue.
