I've tried all scenarios with the update, and noticed some unexpected behaviour. The README says we expect API scenario 2 and Client scenario 1 to fail, but I saw Client 1 works and API 2 works. However, I was unable to get anything for API scenario 1.

I think it might be worth quickly checking all scenarios again with Next.js v13.5.4, and making sure the behaviour you see matches up with what we say in the README. Is this a direct result of changing the version of Next, or do you see the same behaviour in the old example app?
