Question posted in 
So I built a basic app then I was ready to test a "production" prototype and it wouldn’t push to Heroku. It worked fine locally though. So I ran through the steps, pushing a git right after each step, in a different directory and found that it was after I ran hotwire:install that it failed.
Steps:
Ruby version: 3.0.0
Rails Version 6.1.1
rails new yourapp -d PostgreSQL
cd yourapp
git add .
git commit -m "initial"
Heroku create yourapp
git push Heroku master
(you may need to run bundle lock to add linux support then another commit)
--push was successful
bundle add hotwire-rails
git add .
git commit -m "added hotwire gem"
git push Heroku master
--push was successful
rails hotwire:install
bundle install
git add .
git commit -m "ran hotwire install"
git push Heroku master
--push rejected. See output below.
patrick@Patricks-MBP chatapp2 % git push heroku master

Please let me know if you are able to determine the issue. I can see it’s a Module error, but it only happens with hot-wire:install.

So, apparently when you do
hotwire:install, it neglects to also install thecontrollersmodule. Runningyarn add controllerssolved this issue for me. I did also have to be a verified user of Heroku in order to include the Heroku Redis Hobby Dev plan otherwise the Heroku instance would completely crash and I had to reboot the server.I think you need to install webpacker, seems like node_module folder is not there.
To install webpacker
