After completing chapter 6 I began to test the API using Postman. I tried to create a review and got the message ...

    "name": "MongoError",
    "message": "Unknown modifier: $pushAll",
    "driver": true,
    "index": 0,
    "code": 9,
    "errmsg": "Unknown modifier: $pushAll"

After doing some research I found the following solution.

  usePushEach: true

I added this object to my locationSchema like so and then I was able to create new reviews.

const locationSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true,
  address: String,
  rating: {
    type: Number,
    'default': 0,
    min: 0,
    max: 5,
  facilities: [String],
  coords: {
    type: [Number],
    index: '2dsphere'
  openingTimes: [openingTimeSchema],
  reviews: [reviewSchema],
}, {
  usePushEach: true
