session_store.rb
is: YourApplicationName::Application.config.session_store :cookie_store, key: ‘_yourapplicationname_session’
should be: YourApplicationName::Application.config.session_store :cookie_store, :key => ‘_yourapplicationname_session’
wrap_parameters.rb
is: wrap_parameters format: [:json]
should be: wrap_parameters :format => [:json]
