访问数据统计分析-漏洞处理时间统计页面，报错 “Sorry，internal server error！”，查看日志：

   File "/opt/webapp/srcpm/app/main/view.py",line 526, in index_stats_time
      list_stats_retest_time.append(compute_retest_time)'all',vul_report_list_result))
   File "/opt/webapp/srcpm/app/main/view.py",line 612, in compute_retest_time
