从buildSchema切换到GraphSQLSchema时出现GraphQL错误

Question

我正在尝试一个简单的GraphQL原型我有一个简单的查询工作...

import {
  graphql,
  GraphQLSchema,
  GraphQLObjectType,
  GraphQLString
} from 'graphql'

...
var schema = buildSchema(`
type Partner {
    name:String!, 
    id:ID,
    print: String
}
type Query {
    getPartner(name: String!, id: ID) : Partner 
}

我现在尝试使用构建模式的实用方法......

let partnerType = new GraphQLObjectType({
  name: 'Partner',
  fields: {
    name: { type: graphql.GraphQLString },
    id: { type: graphql.GraphQLString },
    print: { type: graphql.GraphQLString}
  }
})

let queryType = new GraphQLObjectType({
  name: 'Query',
  fields: {
    getPartner: {
      type: partnerType,
      args: {
       name: { type: graphql.GraphQLString },
       id: { type: graphql.GraphQLID }
     },
     //resolve: function(_, { id }) {
     resolve() {
       //as a test remove args
       return new Partner("test", 1)
     }
   } 
  }
})

显然我在这里遗漏了一些东西 - 我收到了错误

{
 "errors": [
   {
     "message": "The type of Query.getPartner(name:) must be Input 
Type but got: undefined.\n\nThe type of Query.getPartner(id:) must be 
Input Type but got: undefined.\n\nThe type of Partner.name must be 
Output Type but got: undefined.\n\nThe type of Partner.id must be 
Output Type but got: undefined.\n\nThe type of Partner.print must be 
Output Type but got: undefined."
   }
 ]
}

我得到的输入参数不会被传递给查询？ 有任何想法吗 ？我通过示例代码http://graphql.org/graphql-js/constructing-types/

获得相同的错误
