MongoDB data return [] - mongodb

Question

I'm making a project for my college assignment, but I'm having a trouble while i'm trying to get a data from database called 'project' in 'sitelist' collection from MongoDB.
But for some reason the data i got is only an empty array [ ].
I'm new to MongoDB so i want to know where did i do wrong.
server.js
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const app = express();
const SLDBModel = require('./sldb_schema');
require('./db');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.urlencoded({ extended: true }))
app.use(function (req, res, next)
{
res.setHeader('Access-Control-Allow-Origin','*');
res.setHeader('Access-Control-Allow-Methods','GET, POST, PUT, DELETE');
res.setHeader('Access-Control-Allow-Headers','content-type, x-access-token');
res.setHeader('Access-Control-Allow-Credentials', true);
next();
});
app.get('/api/getList', function (req, res){
SLDBModel.find({},function(err, data){
if(err){
console.log('//app.get// getList error!...');
res.send(err);
}
else{
console.log(data);
res.send(data.map(v => v.toJSON()));
}
});
});
module.exports = app;
app.listen(3000, ()=>{
console.log("SERVER IS ONLINE! ON PORT 3000");
})
sldb_schema.js
var mongoose = require('mongoose');
const Schema = mongoose.Schema;
const SLSchema = new Schema({
S_NAME: {type: String, required: true},
S_ADD: {type: String, required: true},
S_STATUS: {type: String, required: true}
}
);
const SLDBSchema = new Schema({
list: [SLSchema]
}
);
const SLDBModel = mongoose.model('sitelist', SLDBSchema);
module.exports = SLDBModel;
db.js
var mongoose = require('mongoose');
mongoose.connect('mongodb://127.0.0.1/project', {useUnifiedTopology: true, useNewUrlParser: true });
mongoose.connection.on('connected', function () {
console.log('MONGOOSE default connection open');
});
mongoose.connection.on('error', function (err) {
console.log('MONGOOSE default connection error: ' + err);
});
mongoose.connection.on('disconnected', function () {
console.log('MONGOOSE default connection disconnected');
});
process.on('SIGINT', function () {
mongoose.connection.close(function ()
{
console.log('MONGOOSE default connection disconected through app termination');
process.exit(0);
});
});
Data in database called 'project' in collection 'sitelist'
{
"_id" : ObjectId("5ec4672e44f01dcae82c3dde"),
"error" : "0",
"num_rows" : 3,
"list" : [
{
"S_NAME" : "SBOBETH",
"S_ADD" : "sbobeth.com",
"S_STATUS" : "UP"
},
{
"S_NAME" : "GTRCASINO",
"S_ADD" : "gtrcasino.com",
"S_STATUS" : "DOWN"
},
{
"S_NAME" : "SBOBETH",
"S_ADD" : "sbobeth.com",
"S_STATUS" : "DOWN"
},
{
"S_NAME" : "GTRBETCLUB",
"S_ADD" : "gtrbetclub.com",
"S_STATUS" : "UP"
},
{
"S_NAME" : "77UP",
"S_ADD" : "77up.bet.com",
"S_STATUS" : "UP"
},
{
"S_NAME" : "DATABET88",
"S_ADD" : "databet88.net",
"S_STATUS" : "DOWN"
},
{
"S_NAME" : "FAFA855",
"S_ADD" : "fafa855.com",
"S_STATUS" : "UP"
}
]
}
