JSReport请求错误

Question

我正在尝试访问jsreport api以呈现报告模板，但收到以下错误：

{
    body: "{"body":"\"{\\\"template\\\":{\\\"shortid\\\":\\\"B1z8vSImQ\\\"}}\"","status":400,"statusCode":400}",
    code: 500,
    headers: {
        connection: "close",
        content-length: "99",
        content-type: "application/json; charset=utf-8",
        date: "Mon, 16 Jul 2018 14:22:54 GMT",
        etag: "W/"63-y7OYa6jmSZpY//j8j8VDr2CKCZg"",
        server: "nginx/1.15.0",
        x-powered-by: "Express"
    }
}   

下面是我调用api的方式：

const options = {
    method: 'POST',
    //strictSSL: false,
    headers: {
        'Authorization': 'Basic ' + hash,
        'Content-Type': 'application/json',
    },
    body: JSON.stringify({
        template: { shortid: 'B1z8vSImQ' }
    }),
    // auth: {
    //    username,
    //    password
    // }
}

requestify.request('https://gabrielsch.jsreportonline.net/api/report', options)
    .then(response => {

    })
    .catch(error => console.log(error))

有人知道可能会发生什么吗？我在任何地方都找不到任何关于这个的资源。提前谢谢你
