Are you seeing null AAGUIDs, or non-null AAGUIDs? The expected behavior is that we return a null AAGUID. (Note that I changed the title of this bug in Comment 3). There's a separate question of whether we'll change our behavior when https://github.com/w3c/webauthn/issues/1962 is resolved.

Please re-open if you are seeing non-null values.
