useMutation 的 onCompleted 即使出错也会执行

Question

当我使用 useMutation 挂钩并收到响应错误时，将触发 onCompleted 方法。这是正常行为吗？

 const [createPerson] = useMutation(CreatePerson, {
   onCompleted: () => {
     console.log('even onError it`s executed')
   }
 })

根据我们在聊天中的讨论，我认为您已将 Apollo Provider 的错误策略设置为 ignore:

ignore: Ignore allows you to read any data that is returned alongside GraphQL Errors, but doesn't save the errors or report them to your UI.

这就是 GraphQL 错误被忽略的原因。它们只会在使用 none.

的默认策略时被触发
