Middleware

This middleware makes Bugsnag ignore network connection errors raised from Sidekiq jobs. Instead of reporting errors to Bugsnag every time the job retries, we only report these errors if/when the job finally dies. The goal is to eliminate extra noise caused by transient network errors.

class BugsnagSidekiqDeathHandler
  def self.handler
    ->(_job, exception) do
      # The <= operator returns true if the class on the left is the same as OR a subclass of the class on the right
      if BugsnagSidekiqMiddleware::IGNORED_EXCEPTIONS.any? { |e| exception.class <= e }
