graphql突变给出语法错误：预期名称

Question

我想用变量实现突变。但我得到以下错误：

"Syntax Error GraphQL request (3:22) Expected Name, found $ 

2:  mutation { 
3:  createProperty($property) { 
         ^
4:   id 
" 

我的模式绝对不说的名字什么，这就是为什么我认为这个错误就是这么奇怪。我也不会去想graphql的单证/阿波罗是很好。

从客户端调用突变：

const property = { 
    title: 'First house', 
    cost: 849, 
    bedrooms: 3, 
    bathrooms: 2, 
    car_spaces: 1, 
    house_size: 60, 
    }; 

    const createPropertyQuery = 
    graphql(gql` 
    mutation { 
     createProperty($property) { 
     id 
     } 
    } 
    `, { 
     options: { 
     variables: { 
      property, 
     }, 
     }, 
    }); 


    const { data } = await apolloClient.query({ 
    query: createPropertyQuery, 
    }); 

模式：

type Property { 
    title: String! 
    cost: Float 
    user: User 
    bedrooms: Int! 
    bathrooms: Int! 
    car_spaces: Int! 
    house_size: Int! 
} 
input propertyInput { 
    title: String! 
    cost: Float 
    bedrooms: Int! 
    bathrooms: Int! 
    car_spaces: Int! 
    house_size: Int! 
} 

type RootMutation { 
    createProperty (
     property: propertyInput 
    ): Property 
}

你首先应该提到的参数的名字！

mutation CreatePropertyMutatuin($property: propertyInput){ 
    createProperty(property: $property) { 
    id 
    } 
}
