Logs and Argocd Application events showing successful update but image is not actually updated (argocd write back method)

[chathumal-nad]

I see similar open issues where argocd image updater log said it has updated an image but pod itself doesn't roll out new one: #186 #431 #438

The application itself is stored in git as a declarative setup with auto sync options enabled and the registry we are using is a private GCR. We use kustomize for our deployments and as the image tag we have mentioned a previous version (not the latest one) ,in order to check the functionality of the imageupdater. In this case we have setup the write back method as "argocd". Able to see the argocd image updater logs and the application events indicating that the application has been succefully updated but the deployment is always on the mentioned image tag in the kustomize file and never gets updated to te latest image tag. It may be because of the the declarative setup we are using, so we tried the same scenario with "auto sync disbaled" but the response was same; nothing happens to the deployment.

Argocd and Image-updater both deployed in the same cluster and the same namespace.

Argo CD version : 2.2.4 Image updater : 0.12.0

Does anyone know how to make this working? Or isn't this write back method suitable for declarative applications as in this scenario?
