GCR image format not supported?

[Jonathan34]

Describe the bug
I have used skaffold to deploy my image for now and wanted to setup flux.
my deployments have an image that looks like this:
gcr.io/project_id/image_name:tag@sha256:c90d11…

and I get the following error messages from flux
expected image name as either <image>:<tag> or just <image>: invalid image ID

in the k8s manifests, i set the image to image_name:tag

Expected behavior
No message, format is supported.

ok I've set the deployment to gcr.io/project/image:tag and flux is happy again.
guess if you can close this if you want

Duplicate of #885 (although that one is strictly about digests and not a digests + tag combination), has been worked on in in #2162 but shows signs of rot.
