It looks more like the consent flow itself didn't produce a result to store.

Is that a bug in the log line or signifying something about it not releasing any attributes?

That's indicating it has nothing to record, independent of the actual storage service used.

That enables client-side, there's a separate property to turn on local storage. The consent flow can still write to cookies, in limited fashion, so that isn't really itself any answer, I think the issue is the flow itself.
