implementing Type-Safe Configurations for Akka Actors in Scala 2.13.8
I'm wondering if anyone has experience with Can someone help me understand I'm working with issues while trying to implement type-safe configurations for my Akka actors using Typesafe Config in Scala 2.13.8. I want to ensure that my actor's configuration is type-checked at compile time, but I'm having trouble with loading configuration values and dealing with optional fields. I have defined a configuration class like this: ```scala import com.typesafe.config.Config import com.typesafe.config.ConfigFactory case class ActorConfig(actorName: String, maxRetries: Int, timeout: Option[Long]) object ActorConfig { def load(config: Config): ActorConfig = { ActorConfig( actorName = config.getString("actor.name"), maxRetries = config.getInt("actor.maxRetries"), timeout = if (config.hasPath("actor.timeout")) Some(config.getLong("actor.timeout")) else None ) } } ``` When I try to load the configuration in my actor, I encounter a `ConfigException.Missing` behavior, indicating that some path is not found: ``` com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'actor.name' ``` Despite verifying that my `application.conf` file does indeed contain the required keys: ```hocon actor { name = "MyActor" maxRetries = 5 timeout = 3000 } ``` I have also tried using `config.getString("actor.name")` directly in the `main` method to check if the configuration loads correctly, and it works fine, but when I try loading it in the actor, it fails. I'm also unsure about the best practices for handling optional configuration fields and how to ensure that my actor can handle configuration loading gracefully without crashing. Any advice on this would be greatly appreciated! This is happening in both development and production on Ubuntu 22.04. I recently upgraded to Scala stable.
