Python Youtube API commentThreads.update在回复topLevelComment时返回400错误

报告Youtube Api commentThreads.update上可能存在的错误

受影响的API名称：CommentThreads:更新

问题摘要：CommentThreads:update调用此api以更新CommentThreads.list返回的topLevelComment时，我遇到了一个400错误。我在一个内部工具中使用这个API，以允许我回复评论。在过去的几个月里，它运转良好。。。在过去的几天里（~2016-11-07），我的代码没有任何变化，API开始返回400错误。我的所有内部评论系统现在都停止了，因为我不知道如何解决这个问题。我尝试和测试的每一件事都会带来400错误和下面的信息

虽然这可能是暂时性错误，但它通常表示请求输入无效

即使使用API控制台，我也会犯同样的错误！ 我打赌？这是一个暂时的错误，我希望谷歌能够修复

复制问题的步骤：

使用CommentThreads.list检索“heldForReview”线程

尝试更新返回的topLevelComment更改[“topLevelComment”][“snippet”][“textOriginal”]=“some text”。或者，将“moderationStatus”更改为“published”。错误是一样的

使用Python API示例，特别是来自的comment_threads.py文件，可以很容易地发现这种行为

预期输出：线程的顶级注释应该是可见的（在将moderationStatus设置为published之后），并将“some text”作为第一个子注释作为其答案

实际结果：

    {
 "error": {
  "errors": [
   {
    "domain": "youtube.commentThread",
    "reason": "processingFailure",
    "message": "The API server failed to successfully process the request. While this can be a transient error, it usually indicates that the requests input is invalid. Check the structure of the \u003ccode\u003ecommentThread\u003c/code\u003e resource in the request body to ensure that it is valid.",
    "locationType": "other",
    "location": "body"
   }
  ],

  "message": "The API server failed to successfully process the request. While this can be a transient error, it usually indicates that the requests input is invalid. Check the structure of the \u003ccode\u003ecommentThread\u003c/code\u003e resource in the request body to ensure that it is valid."
 }
}
