Bootc throws missing metadata error

[hmrks]

Hi!

I have used the startingpoint repository to create a custom image. Everything seems to work perfectly fine, however when I run sudo bootc status, I get the following error message:

ERROR Reading manifest data from commit: Missing ostree.manifest-digest metadata on merge commit

Note that I haven't changed anything in the GitHub Actions pipeline, or the base image. I have checked the bootc docs, and it seems that once I have a bootc compatible base image (which I assume ghcr.io/ublue-os/silverblue-main is), I can just build on top of that without any special requirements.

Any idea what could cause this issue or how I can further debug this? I am using a private repository for my image so I can not link it.
