Error while using with kustomize: "mapping key "observedGeneration" already defined"

Getting error while trying apply eventing core using kustomize tool : mapping key "observedGeneration" already defined

I usually use kustomize (kubectl -k option) to install knative-eventing, so that I can use my custom container image repo as well can patch knative's k8s manifest files. While it was working fine till 1.15.4, for version v1.16.3, I see the error as below:

error: map[string]interface {}(nil): yaml: unmarshal errors: line 128: mapping key "observedGeneration" already defined at line 97

Expected behavior

• Should be able to use kustomize to install knative eventing components

To Reproduce

• wget https://github.com/knative/eventing/releases/download/knative-v1.16.3/eventing-core.yaml
• create a kustomization file like:

resources:  
  - eventing-core.yaml
images:
  - name: gcr.io/knative-releases/knative.dev/eventing/cmd/controller
    newName: myrepo:8080/knative-eventing/controller
    digest: sha256:1947ff229a3afd39aefd5c58b8c2e05317d6b94bd2f0ea8e560667b261ec934b 

Knative release version
1.16.3

just trying to check the diff between previous versions, I commented out these lines on 3222 and that error is not there.

3222        observedGeneration:
3223                   description: ObservedGeneration is the 'Generation' of the Service that was last processed by the controller.
3224                   type: integer
3225                   format: int64

The fix was merged a while ago #8423, however, the bot is failing to release new 1.16 patch releases https://prow.knative.dev/?job=release_eventing_release-1.16_periodic
