Sorry I replied to quickly; it should have been ‘--disable-authentication’. Why? Because here you’re trying to travel to a commit that’s not part of the “authenticated history”—that is, it’s not a descendant of the “introductory commit”, which is the first commit in history starting from which the “authentication invariant” holds. Hopefully this is clearer; maybe? :-) Cheers, Ludo’.
