Hello Igor,
Thanks for the hint. In the meantime I opted to remove the offending code where the http status call was relevant.
Basically, as per Twitter ToS we removed tweets from our system which aren’t on Twitter anymore. And one indication for that was the 404 result of a tweets status; but as user complained it become clear why couldn’t rely on this metric for now.
However shall the need arise again, I will remember and try to use the other endpoint.
Thank you!
