mailchimp mandrill车把不起作用

Question

我正在尝试使用把手，我完全按照教程说的做了，我的电子邮件似乎根本没有格式化把手。我究竟做错了什么。我在mailchimp发送默认值也是车把。我正在使用JSon中提供的教程示例，只是将代码转换为javascript，但它似乎并没有起作用。

var mandrill = require('mandrill-api/mandrill');
var mandrill_client = new mandrill.Mandrill(MYAPIKEY);
var moment = require('moment-timezone');
var message = {
        "subject": '',
        "from_email": "myemail",
        "from_name": "info",
        "to": [{
                  "email": 'myemail',
                  "name": "Recipient Name",
                  "type": "to"
              }],
        "headers": {
            "Reply-To": "message.reply@example.com"
        },

            },
            {
                "name": "subject",
                "content": "Thank you for your order."
            }
        ],
        "merge_vars": [
            {
                "rcpt": "myemail",
