Reactjs ra数据图SQL simple找不到资源

我尝试使用react admin作为我的管理面板，并使用ra数据graphql simple从graphql API获取。 问题是它找不到我的资源，我遇到了以下错误：

未知资源类别。确保它已在服务器端架构中声明。已知资源是

这是我的密码

App.js

import React, { Component } from 'react';
import buildGraphQLProvider from 'ra-data-graphql-simple';
import { Admin, Resource, Delete, ListGuesser  } from 'react-admin';

import apolloClient from './apolloSetup';

import { CategoryList } from './categories';

class App extends Component {
    constructor() {
        super();
        this.state = { dataProvider: null };
    }
    componentDidMount() {
        buildGraphQLProvider({ clientOptions: { uri: 'http://127.0.0.1:3434/graphql' }})
            .then(dataProvider => this.setState({ dataProvider }));
    }

    render() {
        const { dataProvider } = this.state;

        if (!dataProvider) {
            return <div>Loading</div>;
        }

        return (
            <Admin dataProvider={dataProvider}>
                <Resource name="Category" list={ListGuesser} />
            </Admin>
        );
    }
}

export default App;

这是我的Graphql模式。类别父id始终为1

我应该创建自定义数据提供程序吗？如果是，我应该如何为这个模式创建它？

如果您仍然停留在这一点上，我建议将您的模式减少到只包含类别类型和相关突变。有关ra数据GraphQL simple的预期GraphQL模式格式，请参阅。首先，尝试将资源中的内容交换为此格式。ra data graphql simple非常挑剔，如果它不喜欢您的模式，它只会忽略资源，因此您会在没有资源的情况下收到错误消息。

如果查看源代码，您会注意到，如果资源的类型最少，那么它就是knownResource：

Query {
   Post (id: ID!): Post
   allPosts (page: Int, perPage: Int, sortField: String, sortOrder: String, filter: PostFilter): [Post]

}

在封面下，ra数据graphql simple使用“多元化”库，在评估资源是否可用时，对大小写等极为敏感。如果资源的大小写版本不正确，它将忽略该资源，并且至少包含GET_ONE、GET_LIST查询元素。因此，对于原始帖子“类别”，至少需要所有类别和类别显示为可查询项

Query {
   Post (id: ID!): Post
   allPosts (page: Int, perPage: Int, sortField: String, sortOrder: String, filter: PostFilter): [Post]

}
