ValidationError(Kustomization.spec): missing required fields difficult to debug

[runningman84]

I have a bunch of kind: Kustomization defined in my gitrepo. The kustomize controller fails with an error message like "missing required field...". It is very difficult to find out what file is wrong because 8117172a-dd83-422a-9a54-1db02f6a0601.yaml looks like some random auto generated file...

+1:

nerror: error validating \"bd9fcf53-d698-47ab-9936-ca651cd259a2.yaml\": error validating data: [ValidationError(HelmRelease.spec.chart): unknown field \"sourceRef\" in io.fluxcd.toolkit.helm.v2beta1.HelmRelease.spec.chart, ValidationError(HelmRelease.spec.chart.spec): missing required field \"sourceRef\" in io.fluxcd.toolkit.helm.v2beta1.HelmRelease.spec.chart.spec]; if you choose to ignore these errors, turn validation off with --validate=false\n"}

the name kind/name/namespace could be output it would be human-parsable and unambiguous.

Is there a way to make kubectl output the kind/name/namespace when dry-run fails? If not, then this issue belongs in Kubernetes repo not here.

I agree, this error is not very intuitive with many workloads and people working on one cluster.
