Another panic. I'm focusing on looking at this:

After fixing the panic. I now see these failures instead of panics. Digging into those next...

My next hunch/guess/whatevs is that we make sure pod is up, but the service is not up yet or endpoints are not there, and hence it's actually not ready. Looking at this next...

[vaikas]

all the failed tests are still connection refused:
