This is due to missing [swift] auth in ironic-conductor/ironic.conf, adding bellow part can avoid this issue.
-----------------------------
[swift]
auth_url = http://10.101.96.1:35357
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = ironic
password = qGXIa2OcBlYTRcKKe8z9S5Fe27ghceGN1mQvEjfA
---------------------------------
region_name = RegionOne
valid_interfaces = internal
