Parameterized cascade fail on 20.11.1

{
  q(func:type(App)) @cascade(tnnt.cn) {
    app.cn
    app.tnnt @filter(eq(tnnt.cn, "xyz")) {
      tnnt.cn
    }
  }
}

I think, what you are trying to achieve with this is: Remove all Apps which are not connected to tnnt.cn. And if you apply @cascade for tnnt.cn at root level, it won’t have any effect as tnnt.cn isn’t a root level predicate.
So, maybe you are looking for this:

{
  q(func:type(App)) @cascade(app.tnnt) {
    app.cn
    app.tnnt @filter(eq(tnnt.cn, "xyz")) @cascade(tnnt.cn) {
      tnnt.cn
    }
  }
}

i.e., remove all the app.tnnt which don’t have a tnnt.cn and then also remove all App which don’t have an app.tnnt
