reactjs - 未捕获的错误：操作没有返回数据``, 有错误

Question

我正在使用 React-Relay。我正在做一个返回错误的突变，这完全没问题，但最后我在控制台中遇到了与 react-relay 库相关的错误。

Uncaught Error: No data returned for operation `CreateUserMutation`, got error(s):
A unique constraint would be violated on User. Details: Field name = email

See the error `source` property for more information.

知道我们如何捕捉/避免它吗？
