Hapi js API基本身份验证错误

我在研究hapi js API基本身份验证,并使用hapi文档进行身份验证。我相信我做的每件事都是对的,但我遇到了以下关于未处理PromisejectionWarning的错误。请帮忙

指数js公司

'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);
});
});

包裹json

    "hapi-auth-basic": "^5.0.0",
    "hapi": "^17.1.0"
