If you're using Sidekiq with Rails 6 you may find that Rails 6 ships with non-default queue names for things like ActiveStorage and ActiveMailbox.
It's a little hard to find the documentation for the new queue names, but the new ones are:
action_mailbox_routing action_mailbox_incineration active_storage_analysis active_storage_purge
If you're using sidekiq update your
config/sidekiq.yml to look a little bit like:
--- :verbose: false :concurrency: 1 :max_retries: 3 # Set timeout to 8 on Heroku, longer if you manage your own systems. :timeout: 8 # Sidekiq will run this file through ERB when reading it so you can # even put in dynamic logic, like a host-specific queue. # http://www.mikeperham.com/2013/11/13/advanced-sidekiq-host-specific-queues/ :queues: - critical - mailers - default - action_mailbox_routing - action_mailbox_incineration - active_storage_analysis - active_storage_purge - low
If you're looking for where these are defined, you can see them defined in Rails by calling:
ActiveStorage.queues ActionMailbox.queues[:routing] ActionMailbox.queues[:incineration]
