为什么graphql-compose-mongoose无法识别数组类型？

Question

我正在使用graphql-compose和graphql-compose-mongoose。我有一个mongo集合：

const mongoose = require('mongoose')
const Schema = mongoose.Schema

const PressRelease = new Schema({
  date: {
    type: Date,
    required: true
  },
  articleLink: {
    type: String,
    required: true
  },
  articleTitle: {
    type: String,
    required: true
  }
})

module.exports = mongoose.model('PressRelease', PressRelease, 'PressReleases')

在这里我写我的解析器：

import { composeWithMongoose } from 'graphql-compose-mongoose'
import { schemaComposer } from 'graphql-compose'
import { PressRelease } from 'leaf-schemas'

const PressReleaseTC = composeWithMongoose(PressRelease)
const pressReleasesNewest = PressReleaseTC.addResolver({
    name: 'pressReleasesNewest',
    type: '[PressRelease]',
    resolve: async ({ source, args, context, info }) => {
      return PressRelease.find({}).sort({ date: -1 })
    }
  })

schemaComposer.Query.addFields({
    pressReleasesNewest
})

export { PressReleaseTC }

即使我在graphql游乐场中将返回类型指定为数组，也不是数组类型：

我还尝试指定这种类型：

type: [PressReleaseTC]

这也不起作用。 我在做什么错了？
