发起流程时，保存提示“发起流程失败”

        网上下的一个流程用来练习，在发起的时，点击“保存”会弹出一个提示框，提示“发起流程失败“，如下：
       我查了Server\Log中的日志，具体如下：

请问这个问题如何解决？

要看Server\Log\DefaultEngine这下面的日志才能判断

你用的是什么版本？网上下的是一个什么流程包，有些流程包在发起节点完成事件后面有配置完成事件，你本地可能没有，所以报错。
建议你自己先建一个简单流程测试一下

麻烦帮忙分析下，谢谢。

H3的版本是9.2.7.10511

实名用户_517fa396：H3的版本是9.2.7.10511回到原帖

你这个是自定义表单的,应该是在保存里面做了什么,提示有相同的key值.
初学的话,还是从系统表单开始做起,自定义表单后面再研究.
