What happened

1 参考db_expert_assitant设计AWEL工作流利用Agent Branch operator ,
2 拼接后报错All inputs are empty，后台日志没报错，前台界面报错All inputs are empty
3 目前效果是拼接了10+的自写智能体，单独运行或者串联都是可以的，证明不是智能体问题
4 如下是我拼接截图

What you expected to happen

期望是和串行awel不一样，不是问一句话就全部跑一编=遍智能体，而是精准匹配只跑对应智能体
期望和dify一样，如下截图

How to reproduce

参考我发的json格式文件调试
