256 is clearly not a valid CL code. It's of course always possible that the client sends something perfectly valid and the server interprets it badly for some reason, but it's a lot more likely a priori that the driver just sends something wrong. In any case, since as far as I know no-one has seen that with any other driver, you'd probably want to track that down with the gocql authors.
