Needs rack-session.rb #6
Description
Bundler will only automatically require lib/rack-session.rb based on the gem name. I think you need to add it which requires "rack/session".
gem "sidekiq", path: ".."
gem "concurrent-ruby"
# with Rack >= 3.0
gem "rackup"
gem "rack-session"
% bundle exec rackup simple.ru
bundler: failed to load command: rackup (/Users/mperham/.gem/ruby/3.1.2/bin/rackup)
/Users/mperham/src/sidekiq/bare/simple.ru:18:in `block in <main>': uninitialized constant Rack::Session (NameError)
Did you mean? Rack::RACK_SESSION
