Mongoose: Create() doesn't create document - node.js

Question

Hello this is the first time I post a question.
So basically i'm build an API to manage car(Im doing this as a training for better building API). My connection to the D is made using a singleton which is called once by server and the mongo promises are global(and it works fine for now)
I have my model:
import mongoose, {Schema} from "mongoose";
import mongooseUniqueValidator from "mongoose-unique-validator";
class Voiture{
initSchema(){
const schema = new Schema({
Marque:{
type: String,
require:true,
},
Modele:{
type: String,
require:true,
},
Année:{
type: Number,
require:true,
},
Energie:{
type: String,
require:true,
},
Boite_De_Vitesse:{
type: String,
require:true,
},
couleur_exterieure:{
type: String,
require:true,
},
couleur_intérieur:{
type: String,
},
nombre_De_Portes:{
type: Number,
},
nombre_De_Places:{
type: Number,
},
Prix:{
type: Number,
},
Etat:{
type: String,
require: true,
},
Kilométrage:{
type: Number,
},
prix_location:{
type: Number,
require:true,
}
},{timestamp: true});
schema.plugin(mongooseUniqueValidator);
mongoose.model("voitures", schema);
}
getInstance() {
this.initSchema();
return mongoose.model("voitures");
}
}
export default Voiture;
and I also have services and controllers attached to them
I can get all the documents in the mongoDB Database but I can't create Documents
Here is my service
import voiture from "../models/Voiture"
import mongoose from "mongoose"
class VoitureService{
constructor(){
this.model = new voiture().getInstance();
this.getAll = this.getAll.bind(this);
this.insert = this.insert.bind(this);
}
/**
* GET All voiture
*/
async getAll(query){
let {skip, limit} = query;
skip = skip ? Number : 0;
limit = limit ? Number : 10;
delete query.skip;
delete query.limit;
if(query._id){
try {
query._id = new mongoose.mongo.ObjetId(uery._id);
} catch (error) {
console.log("not able to generate mongoose id with content", query._id);
}
}
try {
let items = await this.model
.find(query)
.skip(skip)
.limit(limit)
let total = await this.model.countDocuments();
return {
error: false,
statusCode: 200,
data: items,
total
};
} catch (errors) {
return {
error: true,
statusCode: 500,
errors
};
}
}
/**
* Insert a car in the Database
*/
async insert(data){
console.log("line 60");
try {
console.log("line 62");
let item = await this.model.create(data, function (err) {
console.log("line 64");
if (err) return handleError(err);
// saved!
console.log("line 67");
});
if (item){
console.log("line 70");
return {
error: false,
item
};
}
} catch (error) {
console.log("error", error);
return {
error: true,
statusCode: 500,
message: error.message || "Not able to create item",
errors: error.errors
};
}
}
}
And this my controller
async addCar(req, res){
let response = await this.service.insert(req.body)
if (res.error) return res.status(res.statusCode).send(response);
return res.status(201).send(response);
}
I tried to log the Item but it gives me undefined
Thanks to all of you !

You can Follow this code
// At Frist, You import **Voiture** Model Then use the model
async insert(data){
console.log("line 60");
try {
console.log("line 62");
let item = await Voiture.create(data, function (err) {
console.log("line 64");
if (err) return handleError(err);
// saved!
console.log("line 67");
});
if (item){
console.log("line 70");
return {
error: false,
item
};
}
} catch (error) {
console.log("error", error);
return {
error: true,
statusCode: 500,
message: error.message || "Not able to create item",
errors: error.errors
};
}
}
