Attempting to Deploy my Rails app to Heroku: ModuleNotFoundError
Question
I'm trying to deploy my rails app to Heroku and I'm running into some error messages that I can't quite make sense of. Does anyone have an idea as to how to resolve this?
Do I need to update my webpacker? This is my first time deploying a Rails app to Heroku so I'm a bit lost as to how best to resolve this issue. Much thanks!
Running: rake assets:precompile
yarn install v1.22.4

Where are your app stylesheets located? I think your clue is here:
ModuleNotFoundError: Module not found: Error: Can't resolve 'stylesheets/application' in '/tmp/build_44a69be4/app/javascript/packs'
Webpacker is looking for 'stylesheets/application.scss' in the /app/javascript/packs directory and can't find it.
