I can reproduce that in our demo environment.

It looks like to be a signatures

see.

docker pull demo.goharbor.io/dockerhub/postgres@sha256:61015780063be263c7b98142d12e61b9c43989abb986c2766ac22044e114293b

unsupported media type application/vnd.in-toto+json

I think on Habor side we should address this particualar problem and future problems that we are going to see in the future. Goal is to disply such information accordingly.

Harbor treats SBOM as an accessory only when it follows the distribution-spec 1.1 standard which image manifest contains the Subject field indicates whose SBOM it is. Otherwise, image manifest without Subject fields will treat as normal image without associate to any other images and read the the arch from the config layer directly.

However, docker currently use application/vnd.in-toto+json at the layer content and assert subject digest in it as below , also have this in index.manifests[0].annotations to track the associations https://docs.docker.com/build/attestations/attestation-storage/#attestation-manifest which not consistent with Harbor.
