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 更新CommentThreads.list 返回的topLevelComment 时，出现400 错误。我在内部工具中使用这个 API 来回复评论。在过去的几个月里它运行良好......在最后几天（~2016-11-07）我这边的任何代码都没有更改，API 开始返回 400 错误。我现在已经停止了我所有的内部评论系统，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让我遇到 400 错误和下面的消息。
“虽然这可能是暂时性错误，但通常表明请求输入无效。”
即使使用 API 控制台，我也遇到了同样的错误！我的赌注？这是一个暂时性错误，我希望 Google 能够修复。
重现问题的步骤：
- 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 示例可以轻松发现此行为，特别是来自https://github.com/youtube/api-samples/blob/master/python/comment_threads.py的文件 comment_threads.py
预期输出：来自 Thread 的顶级评论应该变得可见（在将 moderationStatus 设置为已发布之后）并且将“一些文本”作为第一个子评论作为其答案。
实际结果：
