Running 2023.1, it looks like if you have a trailing slash on your redfish_address variable, ironic will accept it, but sushy will error attempting to instantiate the client:

But when we remove the trailing /, i.e. run something like the next line, it just worked:
openstack baremetal node set --driver-info redfish_address=http://192.168.32.9:8000 ironic0
