Such an object path does not exist on NetworkManager's D-Bus API.
Object paths start with "/org/freedesktop/NetworkManager".
See all object with `d-feet` or `busctl tree
org.freedesktop.NetworkManager`.

Too bad that there was still a user of this API. We wouldn't have
dropped it yet, if we had been aware of existing users. But it's hard
