@revit13, why do you put this file into pkg/action and not into its original place ./internal/experimental/registry/
if you returned the reference.go file, should we return the reference_test.go as well ?

@roytman internal packages are not allowed to be used outside of the helm project thus I placed the file where it can be exposed:

use of internal package helm.sh/helm/v3/internal/experimental/registry not allowed
