反应，aws appsync，阿波罗连接/查询-GraphQL错误：执行超时

Question

嗨，我正在尝试连接和查询来自AWS Appsync服务器的数据，并且总是要加载几分钟，然后出现 GraphQL错误：执行超时。

我尝试了几种方法，但总会导致无限加载。

连接：

Amplify.configure({
    Auth: {
        identityPoolId: config.awsmobile.aws_cognito_identity_pool_id,
        region: config.awsmobile.aws_cognito_region,
        userPoolId: config.awsmobile.aws_user_pools_id,
        userPoolWebClientId: config.awsmobile.aws_user_pools_web_client_id
    }
});


export const client = new AWSAppSyncClient({
    url: config.awsmobile.aws_appsync_graphqlEndpoint,
    region: config.awsmobile.aws_appsync_region,
    auth: {
        type: AUTH_TYPE.AWS_IAM,
        credentials: () => Auth.currentCredentials()
    }
});


export default class App extends Component {
    render() {
        return (
            <div>
                <ApolloProvider client={client}>
                    <Home/>
                </ApolloProvider>
            </div>
        );
    }
}

查询：

export default class Home extends React.Component {
    render() {
        return (
            <Query variables={{bookCode: "GEN"}} query={gql(query)}>
                {({loading, error, data}) => {
                    if (loading) return (
                        <div className="loading">Loading&#8230;</div>
                    );
                    if (error) return <h1>{console.log(error)}Error :(</h1>;

                    console.log(data);

                    return (<h1>Nice</h1>)
                }}
            </Query>
        )
    }
}

我做了另一种方式，这几乎是相似的，如果有必要，我稍后会提供代码
