Error when deploying with no sprockets

[AlecRust]

When I add this gem and deploy to Heroku I get the error:

  rake aborted!
       NoMethodError: undefined method `assets' for #<Rails::Application::Configuration:0x000056068bb95090>

I assume this is because Asset Pipeline/sprockets is disabled in my app?

I only use webpacker. Any chance this gem can handle no Sprockets?

Just ran into this myself. It looks like it was fixed in f89bec4, but no release has been cut which includes that commit. If you want to get around it you can use git as the source in your Gemfile, e.g.: gem 'heroku-deflater', git: 'https://github.com/romanbsd/heroku-deflater.git'
