It's likely due to the club size
It works now. But I was not asking for membership, simply the club metadata

This is happening again !! With the same club
$ curl https://api.chess.com/pub/club/egypt-chess-club | jq

}

Egypt Chess Club end point is broken again.
NOTE this is not a request for the members (which may well be private) but for the main club endpoint, which should return something as it's an active club (https://www.chess.com/club/egypt-chess-club).

{"code":3024,"message":"An internal error has occurred. Please contact Chess.com Developer's Forum for further help https://www.chess.com/club/chess-com-developer-community ."}
