Update multiple entities

Im trying to update all the SubCategories that depends on one Category with bookshelf

const subCategorias = await strapi.query('sub-categoria').model.where({

            categoria: categoria.id

        }).save(data, {

            method: 'update'


It successfully updates, but it does not return a list of SubCategories, instead returns one SubCategory but in this form

attributes: [Object: null prototype] {
    published_at: null,
    updated_at: 2021-07-26T16:47:25.726Z
