Not working with dperson/samba

[fabssor]

Hi,

thanks for the create container. Was exactly what I was looking for.
I got a problem with dperson/ container (https://github.com/dperson/samba):

Failed to check for new Dockerhub image digest: TypeError: Cannot read properties of undefined (reading 'split')
17.12.2023 11:51:33 [error] 	Cannot read properties of undefined (reading 'split')
17.12.2023 11:51:33 [warn] 	Failed to find new digest for image dperson/samba:latest

I think the problem is that the Dockerhub API does not return digest in the repsonse payload (https://registry.hub.docker.com/v2/repositories/dperson/samba/tags/latest)

    ]
}

If I search the docker hub API Spec the digest key is only mentioned per "image" not in the main object in the response.
Any way to work around this? https://docs.docker.com/docker-hub/api/latest/#tag/repositories/paths/~1v2~1namespaces~1%7Bnamespace%7D~1repositories~1%7Brepository%7D~1tags~1%7Btag%7D/get
