A new VM is spun up for each test run, so I don't believe this is an issue with
stale artifacts on the host. I would guess this is more likely some sort of
race condition, and you just happen to be hitting it 50% of the time.

You can probably keep rechecking the patch until you get lucky. But it would be
dangerous to do that without knowing the source of the failure. You will just
most likely keep running into this in future patches then.

The failure looks very odd, with the test expecting a status to be returned but
instead getting a ServerDetail object:
