Route could not be found for application.css / application.js

[Mori]

This issue looks like a zombie of #13 (Assets are not accessible in API-only app), which was closed a year ago. I followed the advice of jam35L in that issue with no effect. Here is the log output:

I tried running rake assets:precompile, and also tried copying the app/assets/ folder into my Rails app and then running rake assets:precompile. These didn't have an effect. I also tried copying the javascripts/ and stylesheets folders into my app's public/ folder. This prevents the Route could not be found error, but the page never loads. Should I try moving the whole engine into my app?

I'm constrained to use Rails 3.2 in this app, is that a known problem? I do have a minimal working graphql endpoint at /queries/admin, tested with curl. Any suggestions beyond those in issue #13?

Thanks!

ActionController::RoutingError (No route matches [GET] "/stylesheets/graphiql/rails/application.css"):

EDIT: My issue was I had require 'sprockets/railtie' commented out in config/application.rb. Uncommenting it fixed the issue for me.

Same issue with Rails 7.0.2, but the solution @alphabt suggested fix it for me.
