Problems deploying to Heroku

1

Have been working on an app with hotwire gem installed. Im using stimulusjs from the app/assets/javascripts folder and also have webpacker installed with turbolinks disabled. I tried to push my code to heroku and got this error everytime I tried to follow other stack overflows for the error but didnt work im thinking its something to do with hotwire, if anyone could help me out and maybe Im missing something obvious

It looks that app/assets/javascripts/libraries is required by app/assets/javascripts/importmap.json.erb but it doesn’t exist in the repo. You can either remove that directory from the importmap file or add it to the repo:

echo > app/assets/javascripts/libraries/.gitkeep
git add app/assets/javascripts/libraries
git commit -m "Adding app/assets/javascripts/libraries
