Summary

Fixes: #72852

This test has been rarely flaky, this change should ensure that we will not see that flakiness anymore, it just add a delay before request is issued.

I think it might make sense to try wrapping this supertest call in a retry block instead of hardcoding delay values. In the past when I have attempted to implement similar solutions I have usually gotten pushback because it goes against the typical pattern used when trying to keep these tests maintainable. cc @spalger

My concern isn't about consistency, it's about the fact that the delay is only necessary if there's something we should be waiting for but we're not waiting for it.

What should these tests be waiting for? Can we add a wait for that thing? If we can't, then we can try retrying.

Delay's seem to work today, but they age out as performance characteristics change and become very difficult to maintain over time.

Is the delay still needed since we've removed the check for the API response and are now just checking the response code?

I don't see anything wrong technically with this test, but I'll defer to @justinkambic to review the meaning of the change here. I worry that we're no longer testing that we "receive expected results"

@spalger yeah we are actually already unit testing that part, it was really hard to reliably test this query.

@spalger we investigated and determined that we have unit tests covering how the server processes this input.

Cool, then maybe we should rename the test
