Error occurs when the argocd plugin checks if the project already exists

As this Argocd project my-quarkus-app-bootstrap already exists, then that fails. If we delete it, then the problem is gone.

I'm wondering how such argocd projects have been created as our templates use the default

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: ${{ values.component_id }}-test
  namespace: ${{ values.gitopsNamespace }}
  finalizers:
    - resources-finalizer.argocd.argoproj.io
spec:
  project: default
