Facebook Messenger 平台发送 API 意外内部错误

Question

我正在开发 Facebook Messenger Platform Send API 框架，但在尝试创建航空公司行程模板 ( https://developers.facebook.com/docs/messenger-platform/send-api-reference/airline-itinerary-template ) 时遇到此错误:

{
 "error": {
   "message": "(#-1) Send API unexpected internal error",
   "type": "OAuthException",
   "code": -1,
   "fbtrace_id": "DBWbw/pHJGv"
 }
}

这是触发它的请求:

我仅在使用此特定模板时遇到此问题。另一个工作得很好。有谁知道可能是什么原因造成的？

谢谢。

Answer 1

我在您的消息 json 中看到以下问题。

1. flight_info部分中的segment_id与passenger_segment_info部分中的segment_id不匹配
2. passenger_id 字段也存在同样的问题。
3. 登机、到达和出发日期格式错误。如果月、日、小时或分钟是个位数，则需要在前面加上 0。

我对上述修复进行了测试，效果很好。这是更新后的示例。
