ruby 2.3.0, rails 5.0.0.beta2, sidekiq 4.1.0

# Gemfile
gem 'sinatra', require: false

# routes.rb
require 'sidekiq/web'
mount Sidekiq::Web => '/sidekiq'

With require 'sidekiq/web' in routes I get an error on server start:

Sorry, my bad. I replied in a hurry.
I can confirm that the Sinatra master branch fixes it.

I was getting this:

Bundler could not find compatible versions for gem "rack-protection":
  In Gemfile:
    sinatra was resolved to 2.0.0.pre.alpha, which depends on
      rack-protection (~> 2.0)

Could not find gem 'rack-protection (~> 2.0)', which is required by gem 'sinatra', in any of the sources.

Have to add this to make it work:

gem 'rack-protection', '~> 2.0', github: 'sinatra/rack-protection', require: false
gem 'sinatra', github: 'sinatra/sinatra', require: false

@sekrett Rack-Protection 2.0.0 is only available using the master branch for now.

gem 'rack-protection', github: 'sinatra/rack-protection'

Beta versions are out now so can start using those instead:
gem "sinatra", ">= 2.0.0.beta2", require: false # https://github.com/mperham/sidekiq/issues/2839

The rack-protection 2.0.0.beta2 seems to get pulled in automatically so no need for the extra declaration.

I've just hit this same issue with ruby '2.6.3' and gem 'rails', '~> 6.0.2.1'
Any ideas on how to resolve this please?
