"get fingerprint" via CLI not working for users other than "me"?

It seems there isn’t any way to view the fingerprints in the web UI, so I’ve tried via the bw CLI. This works:

bw get fingerprint me

But the same for some other user with ID “some-guid-goes-here” does not work:

bw get fingerprint some-guid-goes-here

Always returns “Not found”, even when the ID for the user in question is correct. How can I view other people’s fingerprints?
