Reactjs 来自react apollo hooks的UseCommutation未传递变量

我正在将我的代码从

apollo boost

重构为

react apollo hooks

，并不断出现以下错误：

Variable "$email" of required type "String!" was not provided
Variable "$password" of required type "String!" was not provided

我的重构代码如下：

const [email, setEmail] = useState('')
const [password, setPassword] = useState('')
const variables = {
    data: { email, password }
}
const login = useMutation(LOGIN_MUTATION, {
    variables
})

const onSubmitHandler = async (login, e) => {
    e.preventDefault()
    const authResults = await login()
    localStorage.setItem(AUTH_TOKEN, authResults.data.login.token);
    props.history.push('/') 
}

graphql突变

const LOGIN_MUTATION = gql`
  mutation Login($email: String!, $password: String!) {
    login(data: {
        email: $email, password: $password
        }
    ){
      token
      user {
        id
      }
    }
  }
`

我的模式

login(data: LoginUserInput!): AuthPayload!

---

console.logging电子邮件和密码变量表明它们被正确地传递到

use

文档中有两个变量--

电子邮件

和

密码

。实际上，您要传递给

usemotation

的是一个名为

data

的变量，它不存在

const variables = { email, password }
