Neovim config error: '<eof>' expected near 'local' - linux

Question

I'm setting up Neovim like this guy in this video: https://www.youtube.com/watch?v=vdn_pKJUda8&t=145s&ab_channel=JoseanMartinez
I'm using WSL - Windows subsystem for Linux.
And I have this error in ~/.config/nvim/lua/suleiman/plugins-setup.lua file:
Error detected while processing /home/suleiman/.config/nvim/init.lua:
E5113: Error while calling lua chunk: vim/_init_packages.lua:0:
/home/suleiman/.config/nvim/lua/suleiman/plugins-setup.lua:24: '<eof>' expected near 'local'
stack traceback:
[C]: in function 'error'
vim/_init_packages.lua: in function <vim/_init_packages.lua:0>
[C]: in function 'require'
/home/suleiman/.config/nvim/init.lua:1: in main chunk
And here is the file itself:
vim.cmd([[
augroup packer_user_config
autocmd!
autocmd BufWritePost plugins.lua source <afile> | PackerCompile
augroup end
]])
local status, packer = pcall(require, 'packer')
if not status then
return
end
return packer.startup(function(use)
use('wbthomason/packer.nvim')
use('bluz71/vim-nightfly-guicolors')
if packer_bootstrap then
require('packer').sync()
end
end)
local ensure_packer = function() // This is the line:24
local fn = vim.fn
local install_path = fn.stdpath('data')..'/site/pack/packer/start/packer.nvim'
if fn.empty(fn.glob(install_path)) > 0 then
fn.system({'git', 'clone', '--depth', '1', 'https://github.com/wbthomason/packer.nvim', install_path})
vim.cmd [[packadd packer.nvim]]
return true
end
return false
end
local packer_bootstrap = ensure_packer()
return require('packer').startup(function(use)
use 'wbthomason/packer.nvim'
-- My plugins here
-- use 'foo1/bar1.nvim'
-- use 'foo2/bar2.nvim'
-- Automatically set up your configuration after cloning packer.nvim
-- Put this at the end after all plugins
if packer_bootstrap then
require('packer').sync()
end
end)
plugins-setup.lua
And this is here is the ~/.config/nvim/init.lua file where I require that file:
require('suleiman.plugins-setup')
require('suleiman.core.options')
require('suleiman.core.keymaps')
require('suleiman.core.colorscheme')
I searched on this error, I didn't find the solution.
There isn't supposed to be an error at all I think, because I copied what that guy on that video did.
