Error: Selecting {"stage_id":0,"number":2} on table "group" must return a unique value.

[fluidpb]

I have a double elimination bracket setup and upon updating a match game, this is the error I received. Looking at the raw JSON data, I can see the following:

{
"group": [
    {
      "id": 0,
      "number": 1,
      "stage_id": 0
    },
    {
      "id": 1,
      "number": 2,
      "stage_id": 0
    },
    {
      "id": 2,
      "number": 2,
      "stage_id": 0
    }
  ]
}

This is the error log:

Error: Selecting {"stage_id":0,"number":2} on table "group" must return a unique value.

It seems like the method of base/getter.js is looking for these specific combo:

async getLoserBracket(stageId) {
        return this.storage.selectFirst('group', { stage_id: stageId, number: 2 });
    }

What's the best way to handle this?

What kind of storage implementation are you using?

memory-db. Debugging this some more and it seems like generating a double elimination bracket with the flag consolationFinal: true causes this issue:

await manager.create.stage({
          name: 'Elimination',
          tournamentId: bracket.id, 
          type: (bracket.roundOne === Elimination.Double || bracket.roundOne === Elimination.Double_Bronze) ? 'double_elimination' : 'single_elimination',
          settings: {
            matchesChildCount,
            balanceByes: true,
            // consolationFinal: bracket.bronzeMedal === true,
            consolationFinal: false,
            grandFinal: 'none'
          },
          seeding: rankings.map(ranking => {
            const players: string[] = [`${ranking.player.firstName} ${ranking.player.lastName}`];
            if (ranking.partner) {
              players.push(`${ranking.partner.firstName} ${ranking.partner.lastName}`);
            }
            return {
              id: ranking.id,
              name: players.join(" / "),
              tournament_id: bracket.id,
            }
          }),
        });

Interesting. The 3rd group should have been number: 3
