@josueJouvin toma en cuenta de que este es el nuevo esquema para guardar los outfits generados:

{
  "description": "string",
  "occasions": [
    "string"
  ],
  "name": "string",
  "isAIGenerated": true,
  "combinationItems": [
    {
      "wardrobeItemId": "string"
    }
  ],
  "explanation": "string"
}

En el próximo release se mejorará este esquema, para enviar combinationItems como un array de strings, y no como array de objetos
