getting HTTP parse error, malformed request (): #<Puma::HttpParserError: Invalid HTTP format, parsing fails.>

Hey there, using Ruby on rails. I am getting this when I hit F5. The command line is serving the site properly to http://localhost:12345

HTTP parse error, malformed request (): #<Puma::HttpParserError: Invalid HTTP format, parsing fails.>

I am running the following command inside of VSCODE to start, and it si serving content properly to http://localhost:12345

*** new info, I found out we're running Ruby 2.7.2. Is there a 3.x requirement? ***

bundle exec rdbg --open -n -c -- bundle exec rails s --port 12345

Any ideas? It is definitely serving my development.rb, and my development.rb contains: config.force_ssl = false

Thank you! I need to debug.

could you repro with small rails app or only on your app?
