macOS: Sonoma 14.4.1 MacBook Pro: M3 Pro Neovim: 0.9.5

error message after I select a colorscheme from the list:

Themery error: Could not open file for read: /Users/yanqzh/.config/nvim/v:null

My colorscheme.lua file content:

return {
  "zaldih/themery.nvim", -- a plugin to show a list to switch colortheme
  -- event = "VeryLazy",
  config = function()
    local themery = require("themery")
    themery.setup({
      themes = {
        "modus",
        "tokyonight",
        "everforest",
        "vscode",
        "visual_studio_code",
      },
    })
  end,
}
