I'm having the following issues while updating an NxN relation that has extra fields:

{ method: 'insert',
options: {},
timeout: false,

My object schema:

          export class Pais extends BaseId {
          static tableName = 'Paises';
        
          static tableColumns = {
            id: 'id',
            nome: 'nome',
            moedaId: 'moeda_id'
          };
        
          static jsonSchema = {
            type: 'object',
        
            required: ['nome', 'moedaId'],
        
            properties: {
              nome: { type: 'string', minLength: 1, maxLength: 120 }
            }
          };
        
          static relationMappings: RelationMappings = {
            moeda: {
              relation: Model.BelongsToOneRelation,
              modelClass: Moeda,
              join: {
                from: 'Paises.moeda_id',
                to: 'Moedas.id'
              }
            },
            idiomas: {
              relation: Model.ManyToManyRelation,
              modelClass: Idioma,
              join: {
                from: 'Paises.id',
                through: {
                  from: 'IdiomasFalados.pais_id',
                  to: 'IdiomasFalados.idioma_id',
                  extra: ['oficial']
                },
                to: 'Idiomas.id'
              }
            }
          };
        
          nome: string;
          moedaId: number;
          moeda: Moeda;
          idiomas: Idioma[];
    }

I'm updating this object:

     { id: 1,
        nome: 'Brasil',
        moedaId: '1',
        idiomas: 
        [ { '#dbRef': 1, oficial: true },
          { '#dbRef': 2, oficial: false } ] }

Where idiomas[0] exists in the db and idiomas[1] doesn't.
For some reason it gives a constraint error that it doesn't find idiomas_id., but it exists in the db.
Also, since it's a n x n relation and doesn't have an id column, it tries to insert both relations, and it would fail since the primary key is based on 'pais_id' and 'idioma_id'.

I'm using this command to update (it works fine with insertGraph):

      const knex = Pais.knex();
      const pais = await objection.transaction(knex, async (trx: any) => Pais.query(trx).upsertGraph(model)) as any;

Any way to solve this issue in the current model?
