At least I think thats what this error message means:
HttpError: <HttpError 429 when requesting https://youtube.googleapis.com/youtube/v3/playlists?part=snippet%2Cstatus&alt=json returned "Resource has been exhausted (e.g. check quota).". Details: "Resource has been exhausted (e.g. check quota).">
But my YouTube Data API v3 quotas have not been fully used up:
I have used 31k from my 112k limit and as I understand it the Queries per minute quota is higher than my daily limit, so that should also be no problem.
Am I understanding it right that this error happened because of Quota Limits or is this from another source?
My request basically was creating a new playlist.
