I get an error when trying to reference the javascript packs in my code. Any thoughts on what I might be missing?

application.js

import Rails from "@rails/ujs"
import Turbolinks from "turbolinks"

Rails.start()
Turbolinks.start()

require("jquery-3.5.1.min")
require("jquery-ui-1.12.1")
require("dataTables.fnSetFilteringDelay")
require("jquery.dataTables.columnFilter-1.5.6")
require("application_default")

application.html.erb

 <%= javascript_pack_tag 'application', 'jquery-3', 'jquery-ui-1', 'jquery', 'FixedHeader-2', 'ColVis-1', 'rails': 'reload' %>

You're missing corresponding public/packs/js/*.js files. Two options to fix it:

To just compile your packs and let rails server handle recompilation on refresh

bin/webpack

In development it's better to run dev server. It compiles when your files change.

bin/webpack-dev-server

Note on your file structure and what different tag helpers do:

app/
  assets/                # used by sprockets aka rails asset pipeline
    stylesheets/
      application.css    # stylesheet_link_tag 'application'
                         #  this is not old syntax; very much current and recommended in rails 7
    javascripts/
      application.js     # javascript_include_tag 'application'

  javascript/            # used by rails webpacker
    packs/               # keep this folder neat; don't dump everything in here
      application.js     # javascript_pack_tag 'application'
                         #  use this file to import packages from node_modules
    styles/
      application.css    # stylesheet_pack_tag 'application'
                         #  must be imported in packs/application.js
                         #  import "styles/application"
  
  node_modules/          # use yarn or npm to add js packages, don't put them in 'packs'
