graphql - 为什么 GraphiQL 不能自动完成/查找我的界面字段？

Question

我正在尝试interface在我的schema. 这是schema：

export default new GraphQLObjectType({
  name: "Org",
  fields: () => ({
    name: {
      type: GraphQLString
    },
    paymentType: {
      type: PaymentType,
      resolveType: ({ isCreditCard }) => isCreditCard ? CreditCard : ACH
    }
});

export const PaymentType = new GraphQLInterfaceType({
  name: "PaymentType",
  fields: () => ({
    id: {
      type: new GraphQLNonNull(GraphQLID)
    },
    name: {
      type: new GraphQLNonNull(GraphQLString)
    },
    address: {
      type: new GraphQLNonNull(Address)
    }
  })
});

export const CreditCard = new GraphQLObjectType({
  name: "CreditCard",
  interfaces: [PaymentType],
  fields: () => ({
    number: new GraphQLNonNull(GraphQLInt),
  })
});

export const ACH = new GraphQLObjectType({
  name: "ACH",
  interfaces: [PaymentType],
  fields: () => ({
    routing: new GraphQLNonNull(GraphQLInt),
    accountNumber: new GraphQLNonNull(GraphQLInt),
  })
});

当我转到 myGraphiQL时，我可以看到 中的paymentType和 字段interface，但看不到CreditCard或ACH信息。我一定有什么设置错误？我错过了什么？

例如，您是否在查询中使用类型（CreditCard或ACH）？
