使用Twilio的MMS使用Google App脚本不起作用

Question

我正在尝试使用Google App脚本和Twilio发送彩信。由于某些原因，Twilio没有发送MMS。没有错误被记录。除了我从未收到图像外，一切似乎都按预期运行。我想念什么吗？

function sendText() {

  var messagesUrl = "https://api.twilio.com/2010-04-01/Accounts/AC88563f5e7f405a10c6caa109002d8ac8/Messages.json";

  var payload = {
    "To": '+11234567890',
    "Body" : 'hello',
    "mediaUrl": 'https://c1.staticflickr.com/3/2899/14341091933_1e92e62d12_b.jpg',
    "From" : "+11234567890"

  };

  var options = {
    "method" : "post",
    "payload" : payload
  };
  options.headers = {    
    "Authorization" : "Basic " + Utilities.base64Encode("YOURACCOUNTSID:YOURAUTHTOKEN")
  };

  var value = UrlFetchApp.fetch(messagesUrl, options);
  Logger.log(value)

}

这是我得到的答复
