报错不会跳过，跳过将会影响正确性。你是什么场景，需要跳过报错？

[yuwei43]

那请问如果增量同步报错了要怎么解决呢，需要重新进行一次同步吗

[vinllen]

看下报错的是啥，搜一下faq里面的对应处理

(*Executor).execute:111) Replayer-0, executor-0, oplog for namespace[test.****（表名）] op[c] failed. error type[*mgo.QueryError] error['idIndex' is not allowed with 'autoIndexId':

我是副本集同步到单实例上， 看faq 这个问题还没修复吗？最新版本

[vinllen]

贴一下完整的oplog，还有源端和目的端的MongoDB版本号

[yuwei43]

mongodb版本号都是3.6

autoIndexId字段跟idIndex无法共存，如果源端创建collection时候携带了{autoIndexId: true}，则生成的oplog同时会携带autoIndexId和idIndex。

对于MongoShake来说，此处可以进行判断，如果autoIndexId和idIndex同时存在，则去除autoIndexId字段，依靠idIndex进行创建_id索引。
