Problems setting up fzf-sc

I am trying to set up my Raspberry Pi 400 for Supercollider. I am following madskjeldgaard for his instructions whereby Neovim can be made into an IDE for Supercollider. I’ve got scnvim installed and I’m using Lua for all my config files. I’m trying to set up fzf-sc so that I may have some indexing and that sort of stuff but I run into errors setting it up. I am very new at Lua. All my plugins take place in this file plugins.lua:

-- plugins.lua

return require('packer').startup(function()
    use 'wbthomason/packer.nvim'

local scnvim = require 'scnvim'
local map =
local map_expr = scnvim.map_expr
scnvim.setup {
  keymaps = {
    ['<M-e>'] = map('editor.send_line', {'i', 'n'}),
    ['<C-e>'] = {
      map('editor.send_block', {'i', 'n'}),
      map('editor.send_selection', 'x'),
    ['<CR>'] = map('postwin.toggle'),
    ['<M-CR>'] = map('postwin.toggle', 'i'),
    ['<M-L>'] = map('postwin.clear', {'n', 'i'}),
    ['<C-k>'] = map('', {'n', 'i'}),
    ['<F12>'] = map('sclang.hard_stop', {'n', 'x', 'i'}),
    ['<leader>st'] = map('sclang.start'),
    ['<leader>sk'] = map('sclang.recompile'),
    ['<F1>'] = map_expr('s.boot'),
    ['<F2>'] = map_expr('s.meter'),
  editor = {
    highlight = {
      color = 'IncSearch',
  postwin = {
    float = {
      enabled = true,
  documentation = {                                                                                                                                                                               
    cmd = '/usr/bin/pandoc',                                                                                                                                                             

use { 'ibhagwan/fzf-lua',
  -- optional for icon support
  requires = { 'nvim-tree/nvim-web-devicons' }

-- hjh exp 2023-05-01
use {
	requires = {

-- end exp

when I fire up Neovim I get the error message:
Error detected while processing /home/fearlessleader/.config/nvim/init.lua:

I am using Neovim v0.7.2

Any ideas where I have gone wrong?

                                Thank You For Your Attention

madskjeldgaard mailed me after I brought this up on his git page and said ‘Did you run PackerInstall afterwards? Sounds like it isnt installed’, so I went :PackerInstall and it installed some things, and everything seems to be fine now. Noobie thanks to madskjeldgaard.
