Webpack error on Heroku Deployment

Question

Running my rails app locally works fine. Then I deployed it to Heroku successfully but when opening the app I get the error:

\"We\'re sorry, but something went wron

Answer 1

I had this error, tried to compile and also got :

$ rake assets:precompile RAILS_ENV=production
...
rails aborted!
No such middleware to insert after: ActionDispatch::Static

Solved it thanks to this thread by turning with an ENV

# config/environments/production.rb
config.public_file_server.enabled=true` # ENV['RAILS_SERVE_STATIC_FILES'].present?
