Error saving data from a web API. Registers only the _id

I’m getting information from a web API and I want to save the data to the database.
The problem is that when you save, only the _id is registered.

I’m saving the data like this:

const Datas = db.datas;
.
.
averages = response.data.data[0].quality[0].average.map(a => ({ status: a.status, type: a.type }))

const data = new Datas({
    .
    .
    quality: [{
        "cod": cod,
        "month": month,
        average: averages,
    }],

.
.
.
await data.save();

I tested a console.log(means) and got the array correctly.
I declare the model this way:

var averageSchema = new mongoose.Schema({
  status: String,
  type: String,
  
});
.
.
quality: [{
  average: [{averageSchema}],
}],

The end result is this:

How do I save the other array data correctly?
I appreciate if anyone can help me analyze!
