Without this, you will get an Internal Server Error stating:
Sidekiq::Web needs a valid Rack session for CSRF protection. If this is a Rails app,
make sure you mount Sidekiq::Web *inside* your application routes:
Rails.application.routes.draw do
mount Sidekiq::Web => "/sidekiq"
....
end
If this is a Rails app in API mode, you need to enable sessions.
https://guides.rubyonrails.org/api_app.html#using-session-middlewares
If this is a bare Rack app, use a session middleware before Sidekiq::Web:
# first, use IRB to create a shared secret key for sessions and commit it
require 'securerandom'; File.open(".session.key", "w") {|f| f.write(SecureRandom.hex(32)) }
# now use the secret with a session cookie middleware
use Rack::Session::Cookie, secret: File.read(".session.key"), same_site: true, max_age: 86400
run Sidekiq::Web
