Getting attributes of a OS::Nova::Server raises a 500 if the server doesn't exist.
Created a stack with a single server resource. Specified the public IP (accessIPv4) as an output. Stack show works.
Deleted the server out of band using nova.
Stack show returns a 500 with the following:
{
"explanation": "The server has either erred or is incapable of performing the requested operation.",
"code": 500,
"error": {
"message": "Remote error: NotFound Instance could not be found (HTTP 404) (Request-ID: req-742d8c87-4724-4ba7-9505-b01d21dfaa83)",
