Describe the bug Multiple sources for kustomize seem to not work using v2.9.3.

To Reproduce

I'm using a generator in a monorepo containing the appset and custom overlays. It has following file hierarchy:

.
├── all
│   ├── README.md
│   └── accounts
│       └── proj1.yaml
├── bootstrap.yaml
└── core
    ├── proj-externaldns
    │   ├── component_kustomize.yaml
    │   ├── kustomization.yaml
    │   └── stages
    │       └── proj1-dev
    │           ├── deploymentPatch.yaml
    │           └── kustomization.yaml
    └── dev-applicationSet.yaml

core/dev-applicationSet.yaml (simplified - this is a file in the same repo (proj-mono), referencing the repo again to include another path (core/{{.name}}/stages/proj1-dev)):

- git:
      requeueAfterSeconds: 300
      repoURL: 'https://do.main/company/proj-mono.git'
      revision: HEAD
      files:
      - path: 'core/*/component_kustomize.yaml'
      template:
        metadata: {}
        spec:
          project: proj
          sources:
          - repoURL: '{{.repoURL}}'
            targetRevision: '{{.targetRevision}}'
            path: deployment
          - repoURL: 'https://do.main/company/proj-mono.git'
            targetRevision: HEAD
            path: 'core/{{.name}}/stages/proj1-dev'
          destination: {}

This does generate the proj-externaldns app, but does not add the overlays in core/{{.name}}/stages/proj1-dev.

Expected behavior

Overlays get added using multiple sources.

There is a workaround .

Hi @MauroSoli, it seems this changes kustomize's openAPI sources. I'm not ok to deploy this in production.

Would like to specify multiple entries in the sources[] and have kustomize consume them.

Since this is not natively possible in kustomize, ArgoCD might need to generate some intermediate files and mix them in.

ArgoCD versions 2.10 and below have reached EOL. Can you upgrade and let us know if the issue is still present, please?
