The error message is wrong (given AMD's older interpretation of what a NUL
segment should contain, attribute wise), and actively unhelpful because you
only get it in response to a hypercall where the one piece of information you
cannot provide is the segment selector.
Fix the message to talk about segment attributes, rather than the selector.
