为什么GraphiQL不能自动完成/查找我的界面字段？

Question

我正在尝试在interface中使用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GraphiQL时，我可以看到paymentType以及interface中的字段，但我看不到CreditCard或{ {1}}信息。我必须设置错误吗？我错过了什么？

您是否在查询中使用了类型（ CreditCard 或 ACH ）？
