如何将具有多个对象的状态数组作为参数传递给graphql突变？

我正在创建一个允许用户创建列表的应用程序（所有数据都存储在 mongoDB 上并通过 Apollo GraphQL 访问）；每个列表都有一个属性 listItems，这是一个存储列表中所有项目的数组。

目前，我现在可以移动 listItems 并将它们 setState 放在通过 state.items 访问的数组中，如本视频所示。列表移动由react-sortable-hoc 库中的组件控制

我遇到的问题是采用 listItems 的 state.items 数组并使用突变让 state.items 数组替换数据库中后端相应的 list.listItems 数组。

我相信我可能没有正确设置输入 ListItems 的 typeDefs（我收到错误：Mutation.editListItems(listItems:) 的类型必须是输入类型但得到：[ListItem]!。所以我将其更改为输入而不是类型这可能是一个问题？）

最后，我尝试在下面的 RankList 功能组件中调用 editListItems 突变（包含在 RankList.js 中）“onChange”。我不确定问题出在哪里以及在移动物品时，似乎没有调用突变。请提供建议（让我知道是否应该包含更多信息）！

总的来说，我想知道以下是否可能是一个问题：

• editListItems 的 typeDef 是否正确实现？
• 在这里使用 onChange 是正确的吗？
• 我是否正确调用了突变（在 RankList 组件中）？
• 我是否在 editListItems 突变（在 RankList 组件中）正确传递 state.items ？

typeDefs.js

const { gql } = require("apollo-server");

//schema

module.exports = gql`
  type List {
    id: ID!
    title: String!
    createdAt: String!
    username: String!
    listItems: [ListItem]!
    comments: [Comment]!
    likes: [Like]!
    likeCount: Int!
    commentCount: Int!
  }
  type ListItem {
    id: ID!
    createdAt: String!
    username: String!
    body: String!
  }
  input ListItems {
    id: ID!
    createdAt: String!
    username: String!
    body: String!
  }
  type Comment {
    id: ID!
    createdAt: String!
    username: String!
    body: String!
  }
  type Like {
    id: ID!
    createdAt: String!
    username: String!
  }
  type User {
    id: ID!
    email: String!
    token: String!
    username: String!
    createdAt: String!

    username: String!

    confirmPassword: String!
    email: String!
  }
  type Query {
    getLists: [List]
    getList(listId: ID!): List
  }
  type Mutation {
    register(registerInput: RegisterInput): User!
    login(username: String!, password: String!): User!
    createList(title: String!): List!
    editListItems(listId: ID!, listItems: ListItems!): List!
    deleteList(listId: ID!): String!
    createListItem(listId: ID!, body: String!): List!
    deleteListItem(listId: ID!, listItemId: ID!): List!
    createComment(listId: ID!, body: String!): List!
    deleteComment(listId: ID!, commentId: ID!): List!
    likeList(listId: ID!): List!
  },
  type Subscription{
    newList: List!
  }
`;

list.js（解析器）

async editListItems(_, { listId, listItems }, context) {
      console.log("editListItems Mutation activated!");
      const user = checkAuth(context);

      const list = await List.findById(listId);

      if (list) {
        if (user.username === list.username) {
          list.listItems = listItems;
          await list.save();
          return list;
        } else {
          throw new AuthenticationError("Action not allowed");
        }
      } else {
