scala - Heroku 的 Play/scala 应用停止运行

Question

在本地运行我的 heroku 应用程序时突然遇到这个问题，我的 Play/Scala 应用程序无法运行。看到这个可能导致无法加载 SSL 上下文的错误:

22:27:05 web.1   |  Caused by: com.typesafe.config.ConfigException$WrongType: system properties: path has type OBJECT rather than STRING

简介:

web: target/universal/stage/bin/myapp -Dhttps.port=${PORT} -Dhttp.port=disabled -Dhttps.keyStore.path=conf/generated.keystore

我在远程也遇到同样的错误。如果我在没有 Heroku 的情况下在本地运行应用程序，我看不到任何问题 (sbt -Dhttps.port=$1 -Dhttp.port=disabled ~run)。不清楚它指的是什么配置属性。 Play 版本 2.5.4。

Answer 1

关注帖子后How to configure Play! 2.4.2 HTTPS keystore? , 我将 Procfile 更改为

web: target/universal/stage/bin/myapp -Dhttps.port=${PORT} -Dhttp.port=disabled -Dhttps.keyStore=conf/generated.keystore

它克服了这个错误。也就是说，我从 https.keyStore 变量中删除了“.path”。
