Error: Auth is not defined after having updated the hapi package

[advapiIT]

Hello,
I've upgraded an old Nodejs project to the latest Hapi version... I've read your documentation but I got this error when I start the Nodejs application...

Here's my code

const init = async () => {

    const server = Hapi.server({
        port: port,
        host: 'localhost',
        routes: { cors: { credentials: true } }
    });

   
   

    // include our module here ↓↓, for example, require('hapi-auth-jwt2')
    
    await server.register(require('hapi-auth-jwt2'));

    server.auth.strategy('jwt', 'jwt',
        {
            key: 'SECRETKEYIHAVE', 
            validateFunc: Auth.login_validate,
            verifyOptions: { algorithms: ['HS256'] }// validate function defined above
        });

    server.auth.default('jwt');

    server.route(routes);

    await server.start();
    logger.info('Server running on %s', server.info.uri);

    return server;
};

process.on('unhandledRejection', (err) => {

    logger.error(err.message);
    process.exit(1);
});

init();

and here's my package.json

{
  "name": "aaa-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"

Any suggestion?
