Don't know how to build task 'routes'

Question

I can't execute rake routes even if the routes.rb file is empty. This is the output:

➜ rake routes rake aborted! Don't know how to build task 'routes' (See the list of available tasks with `rake --tasks`)  (See full trace by running task with --trace) 

Output from rake about:

➜ rake about About your application's environment Rails version             6.1.0 Ruby version              ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin19] RubyGems version          3.1.4 Rack version              2.2.3 Middleware                Webpacker::DevServerProxy, Rack::MiniProfiler, ActionDispatch::HostAuthorization, Rack::Sendfile, ActionDispatch::Static, ActionDispatch::Executor, ActiveSupport::Cache::Strategy::LocalCache::Middleware, Rack::Runtime, Rack::MethodOverride, ActionDispatch::RequestId, ActionDispatch::RemoteIp, Sprockets::Rails::QuietAssets, Rails::Rack::Logger, ActionDispatch::ShowExceptions, WebConsole::Middleware, ActionDispatch::DebugExceptions, ActionDispatch::ActionableExceptions, ActionDispatch::Reloader, ActionDispatch::Callbacks, ActiveRecord::Migration::CheckPending, ActionDispatch::Cookies, ActionDispatch::Session::CookieStore, ActionDispatch::Flash, ActionDispatch::ContentSecurityPolicy::Middleware, ActionDispatch::PermissionsPolicy::Middleware, Rack::Head, Rack::ConditionalGet, Rack::ETag, Rack::TempfileReaper, Warden::Manager Application root          /Users/cobexa/app Environment               development Database adapter          postgresql Database schema version   20201219225707

I just discovered that rake routes were deprecated on rails 6.1 in favor of rails routes: https://github.com/rails/rails/commit/41ad613e4c5d6c05f20ac0437564ff0d31ab9f5a
