I\'m trying to deploy a basic app and it\'s not working. Using

I got this error message:

Answer 1

Sometimes Heroku throws an issue on deployment about assets. You can precompile assets and push it to Heroku.

RAILS_ENV=production bundle exec rake assets:precompile

Update:

In case of it doesn't work, make sure to add RAILS_SERVE_STATIC_FILES env. to yr server.

Make it enabled or true nor anything :)

Because in Rails <5.1 production.rb has

config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?

Heroku: App -> Settings -> "Reveal Config Vars"
