Such a weird thing, maybe I need to fully qualify the class.

I’ll have a look at backporting this.

@looorent Are you trying to mount the sidekiq route inside rails?
I faced the same issue when I tried to serve sidekiq web using rackup since it doesn't autoload the gem. Moving it inside rails routes solved it.

[looorent]

@metapraveen Indeed, I should have said that I'm running Sidekiq Web inside using rackup. Here is my start ruby script:

require "sidekiq_unique_jobs/web"
run Rack::URLMap.new("/" => Sidekiq::Web)

@mhenrixon Do you think there is a way to support rackup?

[mhenrixon]

Unless you are using something to autoload your gems you would have to first require "sidekiq-unique-jobs" to make it work @looorent .

[looorent]

Thanks @mhenrixon, this solution works. Here is the rackup script:

require "sidekiq_unique_jobs"
require "sidekiq_unique_jobs/web"
run Rack::URLMap.new("/" => Sidekiq::Web)
