Mongoose find recursive nested object by id - node.js

Question

I'm building a note taking app in which there can be as many nested notes inside one another as the user wants, Similar to folder and file structure expect here everything is a note, I have a note model inside it there is a sub_notes array, I want to be able to find a note whether it is a note at the top of the document or nested inside the sub_notes array, I'm passing the id of the note to which I want to add the next note, I have tried graphlookup but when I use the query it is returning an empty array
This is my Note model
const noteSchema = new Schema({
icon: {
type: String,
},
banner: {
type: String,
},
name: {
type: String,
required: true,
},
user_id: {
type: String,
required: true,
},
date: {
type: Date,
required: true,
default: Date.now,
},
sub_notes: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "notes",
},
],
content: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "blocks",
},
],
});
module.exports = Note = mongoose.model("notes", noteSchema);
This is the query I'm using to find the nested note, The path is a dot seperated string with ids of the notes & the note is the actual note object with the name and other data.
So for ex:
The note
{
id: "123123123",
sub_notes: [{
id: "xyz"
}]
}
So the path here will be 123123123.xyz
var {
note,
path
} = req.body;
var newPath = path.split(".");
const parentNote = Note.findById(newPath[0]);
newPath.splice(0, 1);
console.log(newPath[newPath.length - 1]);
Note.aggregate([{
$match: {
$id: newPath[newPath.length - 1]
}
},
{
$graphLookup: {
from: "notes",
startWith: "$id",
connectFromField: "sub_notes",
connectToField: "id",
depthField: "level",
as: "sub_notes",
},
}
]).exec((err, notes) => {
console.log(notes);
});
