ClearDB mysql提供连接错误AccessDeniedError[SequelizeAccessDeniedError]：拒绝用户访问'；b1xxxxxxxxx@'；本地主机'；

我最近在heroku部署了一台服务器，由于它使用mysql，我将其连接到clearDB，并相应地修改了config.json文件。在部署它之前，我让数据库在本地运行，服务器工作得非常好。但在部署之后，我不得不将数据库更改为cleardb mysql，然后它开始给我各种不同的连接错误。当我只做mysql.createConnection部分时，会弹出一个.connect无错误。同样在mysql工作台上，我可以很好地连接到数据库。在错误消息中，当我确保在配置文件中更改主机，但不确定localhost来自何处时，它显示我正在尝试连接到“b1xxxxxxxx”@“localhost”

这是我的db.js文件：

const config = require('config.json');
const mysql = require('mysql2/promise');
const { Sequelize } = require('sequelize');

module.exports = db = {};

initialize();

async function initialize() {
    // create db if it doesn't already exist
    const { host, port, user, password, database } = config.database;
    const connection = await mysql.createConnection({ host, port, user, password });
    await connection.query(`CREATE DATABASE IF NOT EXISTS \`${database}\`;`);

    // connect to db
    const sequelize = new Sequelize(database, user, password, { dialect: 'mysql' });

    // init models and add them to the exported db object
    db.User = require('../users/user.model')(sequelize);
    console.log(host,port,user,password,database);
    // sync all models with database
    await sequelize.sync();
}

这是我的config.json文件：

{
    "database": {
        "host": "us-cdbr-xxxxxxxxxxx",
        "port": 3306,
        "user": "b1fxxxxxxxx",
        "password": "55dxxxxx",
        "database": "heroku_931ecxxxxxxxxx"
    },
    "secret": "Nhjhgktcdrydcytfgty69pr759edkf867r76fo9g08h940-vhj89ghg&^G&^fgV^%FVDCVGVSgf87vg&8VG*&vFhy&v*)&G)*&g7G*&g*&GV&*)VHVHS(F*jv0-(J()j09JVhSDF(*F*("
}

以下是我的错误消息：
