## ActionList
感谢您的反馈，从帖子的截图来看，您这边已经执行了workflow_demo.sql文件并在设计器设置了外联库了对吗，这边测试了下并没有复现该问题；
从报错信息来看，属于工作流引擎注册问题，一般是后台会启一个java进程，请教下这边在不发送报告后重新运行是否还会报该问题，方便的话可以重装设计器或者收集下设计器日志，这边找开发同事调查下原因。
一看就会，超有用活字格技能：四十五，错误日志收集功能

你好，感谢你的回复，我这边发送报告和不发送都试过，都是不行的。 收到，这边解压后查看工作流相关的日志，怀疑是下面的问题，"在尝试连接到 MySQL 数据库时，用户名或密码不正确，或者用户没有从 localhost 连接到数据库的权限"，大佬可以根据这个异常信息入手排查下；建议也可以创建空白工程，从零搭建工作流学习；
如果还有其他问题，可能需要远程您看一下，您可以先填一下我们这边的1V1申请：https://www.grapecity.com.cn/applyonline，
