I'm trying to deploy my spree project to heroku, but I'm getting the following error message: "Unable to load application: RuntimeError: can't modify frozen Array"
Using the backtrace, this is because deface is calling reject! method on eager_load_paths (deface/railtie.rb:39, using deface 1.1.0). It seems like this is a problem because that eager_load_paths array has already been frozen by railties (lib/rail/engine.rb:571, using rails 5.0.1)?
This doesn't break in development, but for some reason prevents me from opening up my app in production. Any guesses?
