@JackyYangPassion 因为存在错误的边，连接了非法类型的顶点。比如定义变类型friend是person-person的，但是存在一条friend边连接的是person-book。可能是一个类型的顶点覆盖了不同类型的顶点导致，可以在写入数据时打开检查，或者在关闭检查时自行保证数据是合法的。

1. 这里是指 A类型的点和B类型的点 有数值冲突，就是 点类型A，B 均有 value = XXX的吗？

@JackyYangPassion 是的，是这个意思。有两种方式避免此问题

1. 使用primarykey的Id策略，这样id里面会带上label的信息；
2. 将检查id是否存在的开关打开，vertex.check_customized_id_exist=true

感谢，昨天从数据侧确认这是这个问题，使用primarykey的Id策略 再试下
