Better error message if replacement is invalid

Eschewed features

• This issue is not requesting templating, unstuctured edits, build-time side-effects from args or env vars, or any other eschewed feature.

What would you like to have added?

I get this error message:

Error: failed to generate manifests: failed to run kustomize build for "foo/": failed to build kustomization: replacements must specify a source and at least one target

But it does not show me the filename which contains the invalid replacement.

File:

apiVersion: builtin
kind: ReplacementTransformer
metadata:
  name: certificate-namespace-replacement
replacements:
  - source:
      value: mgt-system
    targets:
      - select:
          apiVersion: cert-manager.io/v1
          kind: Certificate
        fieldPaths:
          - metadata.namespace

Why is this needed?

This is needed, so that I solve the issue faster.

Can you accomplish the motivating task without this feature, and if so, how?

yes, somehow I will find the broken file, but this takes longer.

What other solutions have you considered?

Anything else we should know?
