Tie breaks must be valid challonge stats challonge api

[ghost]

To create a tournament i send the tie breaks param in the same mode that the api returns the value. like this. The tournament is a round-robin format:

tie_breaks = [
                "match wins",
                "points difference",
                "match wins vs tied"
            ];

Error: If receive the error tie breaks must be valid challonge stats challonge api.

When do i create a tourmanet tie_breaks param isn't admited?
