Knative eventing issues

[astoycos]

For some reason the first time a Knative service(sink) and source is set up, the eventing webhook pod in project "Knative-serving" Throws the following error

{"level":"error","ts":"2020-05-04T20:20:26.516Z","logger":"eventing-
webhook","caller":"controller/controller.go:409","msg":"Reconcile error","error":"custom resource
 \"eventtypes.eventing.knative.dev\" isn't configured for webhook
 conversion","stacktrace":"knative.dev/eventing/vendor/knative.dev/pkg/controller.
(*Impl).handleErr\n\t/opt/app-
root/src/go/src/knative.dev/eventing/vendor/knative.dev/pkg/controller/controller.go:409\nknative.dev

And the Source fails to forward messages to the sink, however if the source and sink are deleted and then redeployed it seems to work as expected however the error still persists in the eventing webhook pod.
