【问题描述】：

我在 lib/tasks 的 rails 项目中创建 cron 作业

namespace :job do
 desc "TODO"
 task finish_job: :environment do
 jobs = Job.where(end_date:Date.today())
  if jobs != []
    print('Found jobs!')
    
  for job in jobs
        promoter_ids_in_promoter_requests = job.promoters_requests_jobs.where(status: "accept").pluck(:promoter_id)
        
        promoters = Promoter.where(id:promoters).update_all(is_enrolled: false)
    end
else
    print("No jobs!")
end
end 

end

当我运行这个命令时bundle exec whenever --update-crontab 我得到这个错误

这些不是错误，而是弃用警告。如果命令失败，请发布所有错误代码。
