无法使用graphql将数据插入mongodb

Question

我正在使用graphql操场在mongodb中插入一个集合。我遇到架构问题（验证错误）。因此，呼叫不会转发到解析器。我已经附上了下面的代码。

TypeDefs

type User{
        userName: String!,
        password: String!,
        confirmPassword: String!,
        gender: String,
        email:String!,
        dob:String,
}

type Token{
    token: String!
}

type Collection{
    id:String
    products:[Product]

}

type Product{
    name: String!,
    price: Price!,
    brand: String!,
    shippingCost: String!,
    dispatchTime: String!,
    childSku:[Skuobj]!
}

type Skuobj{
    size: String!,
    color:[SkuColors]!
}

type SkuColors{
    color: String!
}

type Price{
    inr: String,
    usd: String
}

input ProductInput{
    name: String!,
    price: PriceInput!,
    brand: String!,
    shippingCost: String!,
    dispatchTime: String!,
    childSku:[SkuobjInput]!
}

input SkuobjInput{
    size: String!,
    color:[SkuColorsInput]!
}

input SkuColorsInput{
    color: String!
}

input PriceInput{
    inr: String,
    usd: String
}

input CollectionInput{
    id:String!,
    product: [ProductInput]!
}

/ Query /

type Query{
    getCurrentUser: User,
    getUser: User!,
    getCollection: Collection!
}

/静音/

类型突变{

    addUser(
        userName: String!,
        password: String!,
        gender: String!,
        email: String!,
        dob: String!): Token

    signupUser(
        userName: String!,
        password: String!,
        gender: String!,
        email: String!,
        dob: String!): Token

    signinUser(
        email: String!,
        password: String!,
    ): Token

    checkValidUserName(
        userName: String!
    ): User

    putCollection(input: CollectionInput):Collection!
}

解析器：-

putCollection: async(_,{id,products})=>{
            console.log('id',id);
            let client = await MongoClient.connect(url, {
                useNewUrlParser: true,
                useUnifiedTopology: true
            });

            let db = client.db(process.env.DB_NAME);
            let res = await db.collection('collection').insertOne({id,products}.collection);
            console.log('res',res);
            return res;
        }

在Graphql游乐场上执行

mutation{
  putCollection(id:"Men",product:[
                {
                    name: "STAR WAR's GRAPHIC TEE'S",
                    price: {
                        inr: "2500",
                        usd: "35.37"
                    },
                    brand: "Levi's",
                    shippingCost: "80",
                    dispatchTime: "5 working days from the date of placing your order",
                    childSku: [
                        {
                            size: "XS",
                            color: [{color:"White"},{color:"Black"},{color:"red"},{color:"orange"}]
                        },
                        {
                            size: "S",
                            color: [{color:"White"},{color:"Black"},{color:"red"},{color:"orange"}]
                        },
                        {
                            size: "M",
                            color: [{color:"White"},{color:"Black"},{color:"red"},{color:"orange"}]
                        },
                        {
                            size: "L",
                            color: [{color:"White"},{color:"Black"},{color:"red"},{color:"orange"}]
                        },
                        {
                            size: "XL",
                            color: [{color:"White"},{color:"Black"},{color:"red"},{color:"orange"}]
                        }
                    ]
                }
            ]

                    )
