undefined method `has_key?' for 10:Fixnum

[vanso-waqar]

Hi, I am getting undefined method `has_key?' for 10:Fixnum error on '/sidekiq/queues' page. When I traced the api/controllers/queues_controller.rb I found an issue with this line

status_counts = Sidekiq::Monitor::Job.where(queue: queue).count(group: 'status')

It works if I change it to

status_counts = Sidekiq::Monitor::Job.where(queue: queue).group_by(&:status)

Please suggest a work around for this.
