prisma type error on union type stored as json

I am trying to convert my Cloud Firestore project to supabase due to some issues I have had with transactions. I have the following types in my code:

export interface RoundOptions {
  name: string;
  scoreToWin: number;
}

export interface BracketOptions {
  name: string;
  defaultScoreToWin: number;
  rounds: RoundOptions[];
}

export interface SingleEliminationOptions {
  type: "single_elimination";
  winAnnotations?: string[];
  brackets: [BracketOptions];
}

export interface DoubleEliminationOptions {
  type: "double_elimination";
  winAnnotations?: string[];
  brackets: [BracketOptions, BracketOptions];
}

export type FormatOptions = SingleEliminationOptions | DoubleEliminationOptions;


And this is my prisma schema I am using for experimentation:
model Tournament {
  id   String @id
  data Json
}


In my code I am trying to do:
      await ctx.prisma.tournament.create({
        data: {
          id: tournament.id,
          data: tournament.formatOptions, // This hsa the type FormatOptions
        },
      });


But I am getting this error. Can someone help me understand whats going wrong?

Solution
Figured it out. In case anybody cares, prisma requires types not interfaces to make this work
