Javascript 连接失败nodejs postgreSQL

我正在尝试将我的NodeJS服务器连接到postgreSQL数据库，我正在使用sequelize进行连接，问题是我遇到以下错误：

Possibly unhandled error: password authentication failed for user "FilipeCosta"
at Connection.parseE (C:\Users\FilipeCosta\desktop\FloraApp\server\node_modules\pg\lib\connection.js:569:11)
at Connection.parseMessage (C:\Users\FilipeCosta\desktop\FloraApp\server\node_modules\pg\lib\connection.js:396:17)
at Socket.<anonymous> (C:\Users\FilipeCosta\desktop\FloraApp\server\node_modules\pg\lib\connection.js:132:22)
at emitOne (events.js:96:13)
at Socket.emit (events.js:188:7)
at readableAddChunk (_stream_readable.js:176:18)
at Socket.Readable.push (_stream_readable.js:134:10)
at TCP.onread (net.js:547:20)

当我尝试使用./bin/www运行服务器时，我得到了这个eror，如sequelize页面中的教程所示

有什么帮助吗？

你能用sequelize将你的代码粘贴到你连接到DB的地方吗？我解决了这个问题，我用新密码创建了一个新用户，但我仍然收到这个错误：未处理的拒绝错误：包含意外。元素必须是模型、关联或对象。
