问题:修改完工作流之后返回工作流列表程序出现异常。
ds版本:apache-dolphinscheduler-3.0.0-alpha-bin
一直转圈圈：F12查看返回值
找到 请求工作流列表的api process-definition
发现错误 10122
查看api日志

发现存在冲突的问题。通过Navicat Premium 15工具我们找到这条数据。发现并不是10001这边条数据值有问题而是变量存在多个。
修改 t_ds_process_definition 这个表的 global_params
刷新页面就可以正常显示了。

问题总结：
变量名一致的情况下提交的时候不会做变量名称(全局和局部变量都不可以一样)的校验，只会做值得校验。需要注意。希望早点修复吧
