sidekiq_retries_exhausted isn't working when running as ActiveJob

[assapir]

Ruby version: ruby-2.6.5
Sidekiq: 6.0.5
Rails: 6.0.2.1

We have a class that use sidekiq as ActiveJob adapter in Application.rb:
config.active_job.queue_adapter = :sidekiq

Then configuring the job like that:

require 'sidekiq/api'
class UploadJob < ApplicationJob

sidekiq_options retry: 3

sidekiq_retries_exhausted do |message, error|
    ...Doing things...
 end

def perform(...)
...

When debugging the work, there is a Proc attached to self.sidekiq_retries_exhausted_block, but when arriving to JobRetry::retries_exhausted, then block = worker&.sidekiq_retries_exhausted_block the block is nil, so it doesn't get called.

We use config.death_handlers as a workaround for that, and it's works.

Please include your initializer and any error message with the full backtrace.

Sidekiq.configure_client do |config|
  config.redis = RedisConnectionStringParser.parse(connection_string)
end
Sidekiq.configure_server do |config|
  config.redis = RedisConnectionStringParser.parse(connection_string)
end

ActiveJob does not support sidekiq_retries_exhausted.

In case anyone runs into this in the future, I got around this by just shimming the behavior back in with the death_handlers config:

# app/config/initializers/sidekiq.rb

Sidekiq.configure_server do |config|
  config.death_handlers << -> (job, exception) do
    worker = job["wrapped"].safe_constantize
    worker&.sidekiq_retries_exhausted_block&.call(job, exception)
  end
end
