正在尝试部署到Heroku，但不确定要做什么

我有一个在Akka HTTP上运行的Scala应用程序，我想将其部署到Heroku。它不起作用，所以我制作了一个超级基本的示例，它只有一个端点（“/”），并返回一个HTML字符串。它只有三个依赖项，都是阿克卡

我在plugins.sbt中定义了sbt本机启动器，在build.sbt中启用了JavaAppPackaging。它在本地运行良好（

heroku local web

），但当我投入生产时，我会得到以下日志：

所以我对它进行了修改，这样就没有办法从shell终止，这对部署来说毫无用处，于是我在程序中添加了一个端口解除绑定钩子。现在我得到以下信息：

在这一点上，我只是不知道该怎么办。似乎无论我尝试什么，程序都无法连接到端口。帮助？

你说的生产是什么意思？马钱斯？在上一次体验中，您似乎将端口从12828更改为53789。您在计算机上打开端口了吗？可能您正试图绑定到heroku上无法访问的某个端口。您可以共享您的主要应用程序代码吗？应用程序配置应注意使用环境变量

PORT
