I've no idea how it got to this, but I've hit this error in my CI:

Any chance you could make a release with this, getting it into release/v1? My workflow is currently failing with this issue, since it still didn't make it into stable. I don't love the idea of using the unstable branch. Normally I'd just wait, but it has already been almost 6 months since, so I figured I'd just make it known that this still occurs in stable.

It might even be worth it to just backport this and make a patch level release if you don't feel ready to release some new features, but this is definitely something worth addressing.

Oh, I haven't realized that this was just a wrong error message for attestations already being present, I thought it was a deeper error somewhere, in this case, you can ignore my earlier message, I thought this was a lot more important as a bug.
