There is a consistent 404 Not Found error when requesting download links via the /clips/download endpoint, even for clips that clearly show auto-generated portrait previews in the Twitch Clip Manager.
Endpoint: GET https://api.twitch.tv/helix/clips/download?id=[CLIP_ID]
Status: 404 Not Found
Observation: The portrait version is processed and visible in the Twitch UI, but the API fails to provide a download_url for the portrait type.
Is the /clips/download endpoint restricted only to manually rendered clips, or is it intended to support auto-generated portrait versions as well? If it’s the latter, why does the API return a 404 instead of the existing portrait assets?
