youtube api - Possible bug when adding a newly created video to a playlist

Question

As of recently, a script has been reporting failures when trying to add a newly created youtube video to a playlist.

The flow is pretty simple:

URL being requested: POST https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&alt=json&part=status%2Csnippet
Video id 'ABC123' was successfully uploaded.
Adding ABC123 to playlist MyPlaylistId
URL being requested: POST https://www.googleapis.com/youtube/v3/playlistItems?alt=json&part=snippet
Payload:
{"snippet": {"resourceId": {"kind": "youtube#video", "videoId": "ABC123"}, "playlistId": "MyPlaylistId"}}
Response:
{'status': '404', 'content-length': '226', 'x-xss-protection': '0', 'x-content-type-options': 'nosniff', 'transfer-encoding': 'chunked', 'vary': 'Origin, X-Origin, Referer', 'server': 'scaffolding on HTTPServer2', '-content-encoding': 'gzip', 'cache-control': 'private', 'date': 'Thu, 17 Sep 2020 12:13:36 GMT', 'x-frame-options': 'SAMEORIGIN', 'alt-svc': 'h3-Q050=":443"; ma=2592000,h3-29=":443"; ma=2592000,h3-27=":443"; ma=2592000,h3-T051=":443"; ma=2592000,h3-T050=":443"; ma=2592000,h3-Q046=":443"; ma=2592000,h3-Q043=":443"; ma=2592000,quic=":443"; ma=2592000; v="46,43"', 'content-type': 'application/json; charset=UTF-8'}
Response content:
{
 "error": {
   "code": 404,
   "message": "Video not found.",
   "errors": [
     {
       "message": "Video not found.",
       "domain": "youtube.playlistItem",
       "reason": "videoNotFound"
     }
   ]
  }
}

Now, the funny part is that the video is actually successfully added to the playlist. I have tested it several times and I get the same result.

Can anyone confirm this bug?

It seems indeed a bug, but, as far as I know, the site for post about bugs with the YouTube APIs is: Issue Tracker¹.

The following link allows you create an entry on Issue Tracker.

It is worth check first if entries exists with the similar issue you're facing and if you find related entries there, please "star" that issue to draw attention to it and track updates, if you'd like.
