If the error type of a fail cause is a throwable we should its causes.

Example code:

import zio._

object Main extends ZIOAppDefault {

  case class FirstException(message: String) extends Exception(message)

  case class SecondException(message: String, cause: Throwable) extends Exception(message, cause)

  case class ThirdException(message: String, cause: Throwable) extends Exception(message, cause)

  val triggerException = ZIO
    .fail(FirstException("First Exception message"))
    .mapError(err => SecondException("Second exception message", err))
    .mapError(err => ThirdException("Third exception message", err))

  override def run: ZIO[Any with ZIOAppArgs with Scope, Any, Any] =
    triggerException
      .catchAllCause(err => ZIO.logErrorCause("log with ZIO Cause", err))
      .exitCode
}
