Describe the bug

vim-plug is my (nev)vim plugins manager, and I have installed tokyonight.nvim and wrote colorscheme tokynight in neovim's init.vim, when nvim started up, an error message appeared:

Error detected while processing C:\Users\LEO\.leovim\conf.d\plugin\schemes-status.vim[312]..ColorScheme Autocommands for "*"..function glyph_palette#defaults#highlight[4]..
<lambda>3:
line    1:
E121: Undefined variable: g:terminal_color_13
Press ENTER or type command to continue

Steps To Reproduce

use vim-plug
install tokyonight
add colorschem tokyonight in init.vim

Expected Behavior

It seams to be glyph_pallete related bug, I have found solution to suppress the error message, just set g:terminal_color_13 before colorscheme command, even an empty string

        let g:terminal_color_13 = ''
        colorscheme tokyonight

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    -- add any other plugins here
  },
})
