Rails web app: Rack app error handling request { GET /packs/js/application-682c14949987e19a8380.js }

Question

When I load the home view (or any view) on my local version of a Rails 6 app, which I'm running with webpack-dev-server through localhost, the page will load, but but not the javascript as I continue to get the following internal server error when webpack calls for application.js in my app/javascript/packs directory:

    2020-07-28 18:04:57 -0500: HTTP parse error, malformed request ():
    #<Puma::HttpParserError: Invalid HTTP format, parsing fails.

    2020-07-28 18:04:57 -0500: Rack app error handling request { GET /packs/js/application-682c14949987e19a8380.js }
    
    #<OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=error: wrong version number>

followed by some more extraneous/vague information. When I run bin/webpack-dev-server, everything (I'm assuming) goes smoothly as so:

ℹ ｢wds｣: Project is running at https://localhost:3000/

ℹ ｢wds｣: webpack output is served from /packs/

ℹ ｢wds｣: Content not from webpack is served from /home/gabe/domus/public/packs

In my application.html.slim file I call the application.js file with javascript_pack_tag:

html
  head
    title Domus
    = csrf_meta_tags
    = csp_meta_tag

    = stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload'
    = javascript_pack_tag 'application', 'data-turbolinks-track': 'reload'

  body
    = yield

And my webpacker.yml file looks like so:

default: &default
  source_path: app/javascript
  source_entry_path: packs
  public_root_path: public
  public_output_path: packs
  cache_path: tmp/cache/webpacker

I'm not too sure what else to try. Any help would be appreciated!

I fixed this by running bin/webpack-dev-server first and then rails s
