Recursive mongoose schema does not result in correct object stores - mongodb

Question

I have a recursive model schema defined in a schema which uses the add() method in the Schema class to incrementally build the schema. It seems to build the paths correctly as shown when I print out the paths. However, when I use the Model defined to store the object in the database, it is missing the inner BNode. Here is a definition of the schema:
import mongoose from 'mongoose';
const BNodeSchema = new mongoose.Schema({
bValue: { type: [Number] },
id: String,
})
const RValue = {
rId: String,
value: Number
}
const ANodeSchema = new mongoose.Schema({
type: {
id: String,
rValues: {
type: Map,
of: RValue
},
}
})
const QuestSchema = new mongoose.Schema({
type: {
_id: { type: String, },
aNode: ANodeSchema,
bNodes: [BNodeSchema],
url: {
type: String
},
id: {
type: String
}
},
},
{ id: false }
)
ANodeSchema.add({ quest: QuestSchema });
const QuestNodeSchema = new mongoose.Schema({
_id: { type: String, unique: true },
quests: { type: [QuestSchema] },
}, {
id: false
})
export const QuestModel = mongoose.model('QuestModel', QuestNodeSchema);
QuestNodeSchema.eachPath(function(path:any) {
console.log(path);
});
{
_id: 12223,
quests:[
{
id: 'Quest-111-111' ,
aNode: {
id: 'A222222',
rValues: {
rId: 'RR1222',
value: 44422
},
quest:{
url: 'https://deptio-opcom',
id: '22222-QST',
bNodes:[{
bValue: 'B22190',
value: 22085
}]
}
}
}
]
}
I have included a sample of the json I am storing in the database. I use a class, not included for brevity to create the equivalent JSON object in the final format to be stored. My feeling is that there is something not quite right with my schema definition. I would be most grateful if someone could help me figure out what I am missing in my definition. Thanks a lot
