Fixes carvel-dev/kapp-controller/issues#1837
Summary
Fixes a 422 Unprocessable Entity validation error triggered by the upgrade to Kubernetes libraries v0.36.0+. Additionally updates golang.org/x/crypto to the latest version.
Background
The upgrade of embedded Kubernetes libraries to v0.36.0 enabled the WatchList feature gate by default. This change forces strict validation on watch requests, specifically requiring the
SendInitialEventfield to be set whenResourceVersionMatchisNotOlderThan.The Issue
The custom translation logic in the packaging API handlers was silently dropping the
SendInitialEventspointer during the conversion frominternalversion.ListOptionstometav1.ListOptions. This resulted in the K8s API server rejecting requests with a422 Unprocessable Entityerror, breaking pipelines.The Fix
SendInitialEventspointer ininternalToMetaListOptswithin both thePackageandPackageMetadataREST registry handlers. Added unit tests to verify that these options are correctly propagated to the client.Test Coverage
