unknown scheme "${v}" (tournament | tournament_nd | gumbel)

Error message

unknown scheme "${v}" (tournament | tournament_nd | gumbel)

What it means

normScheme() found the supplied watermarking scheme string is not one of the supported set (tournament, tournament_nd, gumbel). The empty string defaults to gumbel, so this specifically means a non-empty unrecognized scheme name was passed.
