Description

When generating a scala-akka client for Argo Workflows, I get code with three references to ByteArray. Doesn't look like Scala has that type built-in. I'm able to eliminate the build error by changing it to Array[Byte], but I haven't tested to make sure that client actually works.

Maybe ByteArray just needs to be replaced with Array[Byte]?
