Play Framework comes form, how to process it correctly?

Question

Scala

I receive a form like this:
Form([email protected],Map(action -> user_auth, args[accountName] -> Login, args[code] -> code123, secret_key -> secret_key111)..
I need to correctly extract the values ​​of args.accountName and args.code
I created the following case classes:

case class Args(accountName: String, code: String)
case class MyClass(action: String, args: Args, secret_key: String)

I process like this:

object MyClassForm {
  val form = Form(mapping(
    "action" -> nonEmptyText,
    "args" -> mapping(
      "accountName" -> nonEmptyText,
      "code" -> nonEmptyText
    )(Args.apply)(Args.unapply),
    "secret_key" -> nonEmptyText
  )(MyClass.apply)(MyClass.unapply)
  )
}

But apparently I did something wrong, because. when I receive a request, I see:
error: Form([email protected],Map(action -> user_auth, args[accountName] -> Login, args[code] -> 32112ds, secret_key -> 312),List( FormError(args.accountName,List(error.required),List()), FormError(args.code,List(error.required),List())),None)
What did I do wrong? And how to fix it?

According to the Play Framework documentation,

Note: When you are using nested data this way, the form values ​​sent by the browser must be named like address.street, address.city, etc.

You're trying to parse a form like
this. I guess that's the problem. It seems to me that the simplest solution in this case would be to preprocess the request and change the variable names in it.
