How to update an array of nested documents in MongoDB?

Question

MongoDB

Please tell me how to correctly execute the request so that all the isDeleted fields in the image array and the isDeleted field of the Category are updated.
MongoDB + Mongoose
Category:

{
    "_id": "5785c3e2b40e6ba6a908775e",
    "category_title": "Светлое фентези",
    "category_image_url": "category_2342734.png",
    "design_url": "desing_2.png",
    "__v": 3,

    "image": [
      {
        "_id": "5786042e4854e51ef0b8106c",
        "image_title":"Лесной дракон"
        "image_url": "image.png",
        "isDeleted": false
      },
      {
        "_id": "578600983502e51ef0b810cd",
        "image_title":"Горный дракон",
        "image_url": "image.png",
        "isDeleted": false
      },
      {
        "_id": "20934029580294df1230a89",
        "image_title":"Золотой дракон",
        "image_url": "image.png",
        "isDeleted": false
      }
    ],

    "isDeleted": true
  },

function deleteCategory(req, res, next) {
    model.CategoryModel.findByIdAndUpdate(req.params.id, { isDeleted: true }, function(err, category) {
        if (err) return next(err);
        res.json({ message: "Категория успешно удалена" });
    });
}

function deleteCategory(req, res, next) {
    model.CategoryModel.findByIdAndUpdate(req.params.id, { isDeleted: true }, function(err, category) {
        if (err) return next(err);

        category.image.forEach(item => {
          item.isDeleted = true
        })

        category.isDeleted = true/false // что вам тут нужно

        category.markModified('image') //http://mongoosejs.com/docs/faq.html

        model.CategoryModel.save((err, updatedItem) => {
          if (err) {
            return res.status(400).json({ message: err.message })
          } else {
            return res.json({ message: "Категория успешно удалена" })
          }
        })
    });
}
