是否存在相同问题的现有问题？

• 我已经检查了现有的问题。

分支名称

main

提交ID

c0d71ad

其他环境信息

• 无响应*

实际行为

因为 tasks = TaskService.get_tasks(msg["id"]) 返回空数组，导致 assert tasks, "{} empty task!".format(msg["id"]) 抛出异常，程序终止

预期行为

对抛出的Assert异常进行捕获处理

重现步骤

1、启动ragflow_server、task_executor、前端项目
2、在系统页面知识库->数据集中新增一个待解析文件，并点击执行按钮
3、在task_executor下的控制台中，提示报错
