Hapi js API basic authentication error - node.js

Question

I was researching about the hapi js API basic authentication and i'm using Hapi documentation about the authentication. I believe i did everything right but i'm getting following error saying about UnhandledPromiseRejectionWarning. Please help
index.js
'use strict';
const Bcrypt = require('bcrypt');
const Hapi = require('hapi');
const Basic = require('hapi-auth-basic');
const server = new Hapi.Server({
host: 'localhost',
port: 3000
})
const users = {
john: {
username: 'john',
password: '$2a$10$iqJSHD.BGr0E2IxQwYgJmeP3NvhPrXAeLSaGCj6IR/XU5QtjVu5Tm',
name: 'John Doe',
id: '2133d32a'
}
};
const validate = function (request, username, password, callback) {
const user = users[username];
if (!user) {
return callback(null, false);
}
Bcrypt.compare(password, user.password, (err, isValid) => {
callback(err, isValid, { id: user.id, name: user.name });
});
};
server.register(Basic, (err) => {
if (err) {
throw err;
}
server.auth.strategy('simple', 'basic', { validateFunc: validate });
server.route({
method: 'GET',
path: '/',
config: {
auth: 'simple',
handler: function (request, reply) {
reply('hello, ' + request.auth.credentials.name);
}
}
});
server.start((err) => {
if (err) {
throw err;
}
console.log('server running at: ' + server.info.uri);
});
});
package.json
"bcrypt": "^1.0.3",
"hapi-auth-basic": "^5.0.0",
"hapi": "^17.1.0"

If you want that code to work you will have to use a version lower than 17, i.e (16.6.2) or either look for the code updated to the hapi version you are using.
const Bcrypt = require('bcrypt');
const Hapi = require('hapi');
const users = {
john: {
username: 'john',
password: '$2a$10$iqJSHD.BGr0E2IxQwYgJmeP3NvhPrXAeLSaGCj6IR/XU5QtjVu5Tm', // 'secret'
name: 'John Doe',
id: '2133d32a'
}
};
const validate = async (request, username, password, h) => {
if (username === 'help') {
return { response: h.redirect('https://hapijs.com/help') }; // custom response
}
const user = users[username];
if (!user) {
return { credentials: null, isValid: false };
}
const isValid = await Bcrypt.compare(password, user.password);
const credentials = { id: user.id, name: user.name };
return { isValid, credentials };
};
const main = async () => {
const server = Hapi.server({ port: 4000 });
await server.register(require('hapi-auth-basic'));
server.auth.strategy('simple', 'basic', { validate });
server.auth.default('simple');
server.route({
method: 'GET',
path: '/',
handler: function (request, h) {
return 'welcome';
}
});
await server.start();
return server;
};
main()
.then((server) => console.log(`Server listening on ${server.info.uri}`))
.catch((err) => {
console.error(err);
process.exit(1);
});
