Rails quitting loop but not logging anything even though rescue StandardError is present - mystery

Question

I have a method like so:

  def self.perform
    total_done = 0

    all_user_roles = UserRole.all
    user_roles_count = all_user_roles.count

    Rails.logger.info "Going to loop #{user_roles_count} times"

    all_user_roles.each do |user_role|
      Rails.logger.info "starting the loop..."

      if user_role.invalid?
        Rails.logger.info "Skipping, role invalid."
        next
      end

      role_name = RoleService.send(
        :role_name,
        role: user_role[:role],
        project: user_role.project
      )

      existing_role = RoleService.get_for_user(user_role.user, project: user_role.project)
      if existing_role.present?
        Rails.logger.info "Skipping role because it already exists."
        next
      end

      RoleService.set_for_user(
        user_role.user,
        project: user_role.project
      )

      migrated_roles += 1
    end

    Rails.logger.info "DONE"
  rescue StandardError => e
    Rails.logger.error("Error!")
  end

To my surprise, I see it should loop 1000 times:

>>> Going to loop 1000 times

...but neither the DONE message nor the Error at the end are logged. I see it runs 105 times, and then no more messages in the log.

What could be happening here? Is there a way for something to be raised from one of those service calls and not be caught by the general rescue at the end?

I'm running out of ideas...

Thanks!
