Neovim version (nvim -v)

0.9.2

Operating system/version

EndeavourOS

Describe the bug

When in lazy.nvim's popup window viewing plugins and pressing enter causes an error to occur, preventing me from viewing information about the plugin:
Error log from Neovim:

Error executing vim.schedule lua callback: vim/shared.lua:0: s: expected string, got nil

Press ENTER or type command to continue

After encountering that error, it becomes impossible to view any other plugins or the plugin itself, regardless of how many times the enter key is pushed.

Steps To Reproduce

1. Open Neovim
2. Open up lazy.nvim using :Lazy
3. Move cursor over plugin that uses keys to specify lazy loading
4. Press enter
5. Notice how the error occurs
6. Move cursor over to different plugin
7. Press enter
8. Notice how nothing happens

Expected Behavior

An error should not show, and I should be able to view information about the plugin when pressing enter with my cursor on the selection, viewing things like the directory, url, version, tag, etc. along with any other plugins

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
	vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
	"folke/tokyonight.nvim",
	-- add any other plugins here
	{
		"numToStr/Comment.nvim",
		config = true,
		keys = {
			{ "gc", mode = { "n", "v" } },
			{ "gb", mode = { "n", "v" } },
		},
	},
}
require("lazy").setup(plugins, {
	root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here
