Note: #8893 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (161f9cb), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

Looks similar to #9510

I just added a retry for data science onramp in #9496 - we can likely use the same approach here - same problem, same product
