Mongoose: Array with 2 different nested schemas as key-value - node.js

Question

I'm trying to insert data from Google Reply to Reviews API into MongoDb using mongoose but some of the objects inserted have empty fields and some of them are nested key-value objects inside an Array which I don't know how to catch.
This is the JSON response from the API:
{
"reviews": [
{
"reviewId": "19940672-2a0f-470b-8760-05ce91add518",
"authorName": "el piculin 357",
"comments": [
{
"userComment": {
"text": "\tEs bueno y los logos son faciles de adivinar",
"lastModified": {
"seconds": "1675041753",
"nanos": 386000000
},
"starRating": 5,
"reviewerLanguage": "es",
"device": "grandpplte",
"androidOsVersion": 23,
"appVersionCode": 99,
"appVersionName": "2.5.0",
"deviceMetadata": {
"productName": "grandpplte (Galaxy J2 Prime)",
"manufacturer": "Samsung",
"deviceClass": "FORM_FACTOR_PHONE",
"screenWidthPx": 540,
"screenHeightPx": 960,
"nativePlatform": "ABI_ARM_V7,ABI_ARM",
"screenDensityDpi": 240,
"glEsVersion": 196609,
"ramMb": 1407
}
}
}
]
}
]
}
This is my Schema (review.model.js):
const mongoose = require("mongoose");
const ReviewSchema = new mongoose.Schema({
reviewId: { type: String, default: '', unique: true },
authorName: { type: String, default: '' },
userComment: {
text: { type: String, default: '' },
lastModified: {
seconds: { type: String, default: '' },
nanos: { type: Number, default: 0 },
},
starRating: { type: Number, default: 0 },
reviewerLanguage: { type: String, default: '' },
device: { type: String, default: '' },
androidOsVersion: { type: Number, default: 0 },
appVersionCode: { type: Number, default: 0 },
appVersionNumber: { type: String, default: '' },
thumbsUpCount: { type: Number, default: 0 },
thumbsDownCount: { type: Number, default: 0 },
},
developerComment: {
text: { type: String, default: '' },
lastModified: {
seconds: { type: String, default: '' },
nanos: { type: Number, default: 0 },
}
},
appInformation: {
packageIdentifier: { type: String, default: '' }
}
});
const Review = mongoose.model("Review", ReviewSchema);
module.exports = Review;
Another thing that I tried:
const mongoose = require("mongoose");
const AppInformationSchema = new mongoose.Schema({
packageIdentifier: { type: String, default: '' }
});
const DeveloperCommentSchema = new mongoose.Schema({
text: { type: String, default: '' },
lastModified: { LastModifiedSchema }
});
const LastModifiedSchema = new mongoose.Schema({
seconds: { type: String, default: '' },
nanos: { type: Number, default: 0 },
});
const UserCommentScehma = new mongoose.Schema({
text: { type: String, default: '' },
lastModified: { type: LastModifiedSchema },
starRating: { type: Number, default: 0 },
reviewerLanguage: { type: String, default: '' },
device: { type: String, default: '' },
androidOsVersion: { type: Number, default: 0 },
appVersionCode: { type: Number, default: 0 },
appVersionNumber: { type: String, default: '' },
thumbsUpCount: { type: Number, default: 0 },
thumbsDownCount: { type: Number, default: 0 }
});
const ReviewSchema = new mongoose.Schema({
reviewId: { type: String, default: '', unique: true },
authorName: { type: String, default: '' },
comments: [UserCommentScehma, DeveloperCommentSchema],
appInformation: { AppInformationSchema }
});
const Review = mongoose.model("Review", ReviewSchema);
module.exports = Review;
But I get an error when trying to implement it like that:
ReferenceError: Cannot access 'LastModifiedSchema' before initialization
What is the right way of implementing it?

Answer 1

As UserCommentScehma is under userComment itself, so you need to consider this structure in the schema as well.
const ReviewSchema = new mongoose.Schema({
reviewId: { type: String, default: '', unique: true },
authorName: { type: String, default: '' },
comments: [{ userComment: UserCommentScehma }, DeveloperCommentSchema],
appInformation: { AppInformationSchema }
});
