在 Ktor 0.9.3 应用程序中，我希望.conf为不同的环境提供不同的文件，我在其中扩展了一个主.conf文件。但是，我收到以下异常：

Exception in thread "main" com.typesafe.config.ConfigException$NotResolved: called valueType() on value with unresolved substitutions, need to Config#resolve() first, see API docs
    at com.typesafe.config.impl.ConfigDelayedMerge.valueType(ConfigDelayedMerge.java:46)

    at io.ktor.server.netty.DevelopmentEngine.main(DevelopmentEngine.kt:13)
    at ApplicationKt.main(application.kt:24)

这是我的application.conf文件：

ktor {
    deployment {
        port = 8080
        port = ${?PORT}
        watch = [ website ]
    }
    application {
        modules = [ ApplicationKt.module ]
    }
}

ui {
  hotreload {
    enabled = false
    path-prefix = "http://localhost:3000"
  }
}

以及我想使用的扩展它：

include "application.conf"

ui.hotreload.enabled = true

任何想法出了什么问题以及如何解决它？

根据我在Ktor 的GitHub 页面上打开的问题，这是一个已知的错误，修复它的 PR已经合并，所以它应该在下一个版本中修复。事实上，它在版本中按预期工作0.9.4-alpha-2
