Apollo Graphql自定義標量JSON - 抱怨「TypeError：type.getFields不是函數」

Question

我正在使用apollo-express graphql服務器。我試圖整合模塊'graphql-type-json'，但是當我遵循this description關於如何集成時，我嘗試了很多東西，但似乎這個類型沒有被正確地傳遞給解析器 - 但我已經命中我的調試中有一堵牆，可以使用一點幫助。這是我正在做的事情的總結。

import { makeExecutableSchema } from 'graphql-tools'; 
const GraphQLJSON = require('graphql-type-json'); 
//Have also tried import GraphQLJSON from 'graphql-type-json'; 

const schema = ` 
scalar JSON 

type Device { 
    deviceconfig: JSON 
} 

type Query { 
    foo: Foo 
} 
`; 

const resolveFunctions = { 
    JSON: GraphQLJSON, 
    //JSON: {return GraphQLJSON} stops error but other issues come up... 
    Query: ... 
}; 

const jsSchema = makeExecutableSchema({ 
typeDefs: schema, 
resolvers: resolveFunctions, 
resolverValidationOptions: { 
    requireResolversForNonScalar: false, 
}, 
allowUndefinedInResolve: true, 
printErrors: true, 
}); 

不知道，如果是相關的，但也有與我的新公共管理的幾個問題：

我解決了解析器

JSON: { 

    __serialize(value) { 
     return GraphQLJSON.parseValue(value); 
    } } 

定製標JSON這樣，它的工作罰款我。我認爲它會幫助你
