Liveness probe failed in k8s v1.28 and 1.29 using kopf 1.37.3

Long story short

Hi @nolar ,

Our operator running on both k8s v1.28 and 1.29 has started failing the liveness probe at the startup after upgrading kopf to 1.37.3 along with Python 3.13. Switching back to 1.37.2 works as expected. There might be an incompatibility with the K8s version. I couldn't find a particular log from the output. I also tried the latest version of aiohttp==3.11.7 but it didn't help much.

1.37.3
