具有DynamoDB的NodeJS API-配置中缺少区域，但已设置

Question

I created a NodeJS API and when I start my server, I can do my HTTP requests with success to my AWS Dynamo DB. But about twenty seconds after the request's response, the server crashes and says "missing region in config"

My requests are successful so why does it do that ?

This is my server.js :

const express = require('express');
const config = require('./config');
const cors = require('cors');
const createError = require('http-errors');
const bodyParser = require('body-parser');
const app = express();

// parse requests
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

//Enable CORS for all HTTP methods
app.use(cors());

// Routes
require('./routes/survey.route.js')(app);
require('./routes/user.route.js')(app);

// Handle defaut request without any route or params
app.get('/', (request, response) => {
     response.send("Welcome to my API !");
});

// Listen on port 8080 for connections
app.listen(config.serverPort, (err) => {
    if (err) {
        return console.log('something bad happened', err);
    }

    console.log(`server is listening on ${config.serverPort}`);
});

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    console.log(req);
    next(createError(404));
});
module.exports = app;

Each of my routes' requests include the file database.js

Which has code :

// Configuring the database
const AWS = require('aws-sdk');
const config = require('./config');

AWS.config.update({
    accessKeyId: config.aws_accessKeyId,
    secretAccessKey: config.aws_secretAccessKey,
    region: config.aws_region
});

And this is my config.js :

module.exports = {
    baseUrl: '/api',
    serverPort: 8080,
    aws_accessKeyId: 'XXXXX',
    aws_secretAccessKey: 'XXXXX',
    aws_region: "us-east-2"
};

module.exports = AWS;

I can't find why my app crashes in both local and EC2 instance...

Haven't been able to fix this since few days of searches
