Rails 4.2 compatibility

See original GitHub issue

Got the following deprecation warnings and errors after upgrading to rails 4.2.0.

DEPRECATION WARNING: The configuration option `config.serve_static_assets` has been renamed to `config.serve_static_files` to clarify its role (it merely enables serving everything in the `public` folder and is unrelated to the asset pipeline). The `serve_static_assets` alias will be removed in Rails 5.0. Please migrate your configuration files accordingly.

Also have this error in 2022, but only in GitHub CI. Locally it works well.
