Not working with extra registry parameter in helm value.

[crazy-canux]

Describe the bug

when there are three parameters in helm value, it's not working.

To Reproduce

    argocd-image-updater.argoproj.io/image-list: myalias=my-registry/my-repository:latest
    argocd-image-updater.argoproj.io/myalias.update-strategy: digest
    argocd-image-updater.argoproj.io/myalias.force-update: true
   argocd-image-updater.argoproj.io/myalias.helm.image-name: backstage.image.repository
   argocd-image-updater.argoproj.io/myalias.helm.image-tag: backstage.image.tag

in helm value:

    backstage:
        image:
            registry:
            repository:
            tag:

Expected behavior update image in argocd.

Additional context without image-name and image-tag annotation, will get another issue. new image detected, but not updated in argocd.
