[Bug]: Assertion causes the program to terminate

Is there an existing issue for the same bug?

[X] I have checked the existing issues.

Branch name

main

Commit ID

c0d71adaa2c6c8d5b54d2ec5e4fe51ad0ea07c01

Other environment information

No response

Actual behavior

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，程序终止微信截图_20240524172611

Expected behavior

对抛出的断言异常进行捕获处理

Steps to reproduce

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
