我正在构建一个Node/Postgres应用程序，我正在部署到heroku。我在尝试打开生产中的应用程序时收到超时错误。根据Heroku，我收到的错误来自数据库或端口连接问题。我相信我的数据库连接没问题，我得到一个连接成功的日志。不确定我是否与postgres集成导致PORT连接问题。将节点/ Sequelize应用程序部署到heroku - 问题PORT
这里是在Heroku上的日志错误（不是很有用）

谢谢！
****在部署后成功连接到postgres的其他日志。我想要注意的是，这不是在试图打开应用程序时，我没有在应用程序打开时在postgres上收到任何形式的服务器。

***** UPDATE
我相信这是一个港口的问题。我在js文件中放置了几个日志，并且所有内容都可以顺利地记录在models/index中，但是现在我的www文件中已经有日志了。我相信这就是问题所在。
