Scala 3 support

I have the following line in my code:

private val deployments = Deployments(config.get[List[Deployment]]("deployments").valueOrElse(List.empty))

where Deployment is a case class with some String fields and Deployments is a case class with one field List[Deployment]. Compilation of the code pasted above fails with

[error] 21 |  private val deployments = Deployments(config.get[List[Deployment]]("deployments").valueOrElse(List.empty))
