The uniqueness middleware produces validation failure errors in a different format than other validations.
This was uncaught as the concurrency test cases didn't have any assertions.
4a4a1172590e009a3f644dc94a70cbe3472223e4 demonstrates the failure. It interestingly only shows a single failure which I suspect is because the actual validations prevented the other test's duplicate registration attempt.
