Perfect.

The playground unfortunately shows:

{
  "error": "Response not successful: Received status code 404"
}

although we send quite a nice message back:

{"errors":[{"message":"Unknown keyspace 'yourKeyspace'"}]}

Can it be that something is missed here, I usually get very good error messages in the playground when using the GQL?

I think that's expected behavior.
When querying for non-existing keyspace:

When querying for existing empty keyspace:

So both situations look ok.
