How to update data using aggregate?

Question

Node.js

There is this code:

reviewSchema.statics.getAverageRating = async function(card) {
  console.log(card);
  const obj = await this.aggregate([
    {
      $match: { card: card }
    },
    {
      $group: {
        _id: "$card",
        averageRating: { $avg: "$rating" },
        ratingParams: { $avg: "$ratingParams" }
      }
    }
  ]);

  try {
    await this.model("cards").findByIdAndUpdate(card, {
      averageRating: obj[0].averageRating,
      ratingParams: obj[0].ratingParams
    });
  } catch (err) {
    console.log(err);
  }
};

When a review is created, another collection is searched and the data changes, as I understand it. The problem is that it only works like this (with one parameter)

reviewSchema.statics.getAverageRating = async function(card) {
  console.log(card);
  const obj = await this.aggregate([
    {
      $match: { card: card }
    },
    {
      $group: {
        _id: "$card",
        averageRating: { $avg: "$rating" }
      }
    }
  ]);

  try {
    await this.model("cards").findByIdAndUpdate(card, {
      averageRating: obj[0].averageRating
    });
  } catch (err) {
    console.log(err);
  }
};

But I need to update 2 parameters. But when saving, one parameter is changed, and the other becomes null. The thing is that I am passing an object as the second parameter. Perhaps this is causing an error? How to process it correctly?
