How get results from all rounds?

Hi,

I have a problem. I cant get results from all rounds from tournament. When I call:
https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419

In rounds section I got only 1 url:

"rounds":["https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419/7"]

When I call for example: https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419/1

I got empty results. How get rounds 1,2 etc?
