youtube api 无法上传到我的频道

Question

我正在使用 C# (.net 7) 和 google api 包上传但无法上传到特定频道。好像忽略了

video.Snippet.ChannelId

video.Snippet.ChannelId = "UCfzaSOpwn0iY15Lmu3bLtkA";

每当我尝试以这种方式上传时，它都会上传到个人帐户（默认的 youtube 频道）

我也试过用

OnBehalfOfContentOwnerChannel

和

OnBehalfOfContentOwner

            var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");

            videosInsertRequest.OnBehalfOfContentOwnerChannel = "UCXXXXXXXXXX";
            videosInsertRequest.OnBehalfOfContentOwner = "{ChannelHandler*}";

我收到以下错误；

An error prevented the upload from completing.
The service youtube has thrown an exception.
HttpStatusCode is Forbidden.
Google.Apis.Requests.RequestError

我很确定我错过了什么，但不确定是什么。我有类似的问题来下载我自己的字幕，但我假设这也会解决这个问题。

*频道处理程序是您在带有@的频道页面中看到的内容，例如https://www.youtube.com/@VOLEapp我假设它是VOLEapp

谢谢，
