`contentDetails` -> `duration` always returns 0#299

For a couple of weeks, impossible to get the duration of a YT video. It always returns 0. Perfectly repeatable. e.g. https://yt.lemnoslife.com/videos?part=contentDetails&id=n8vmXvoVjZw ```json { "kind": "youtube#videoListResponse", "etag": "NotImplemented", "items": [ { "kind": "youtube#video", "etag": "NotImplemented", "id": "n8vmXvoVjZw", "contentDetails": { "duration": 0 } } ] } ```
