missing region in section of %s

Error message

missing region in section of %s

What it means

Configuration guard in OpenstackConfig.GetServiceConfig: the requested service section was found in the OpenStack config file but its region key is empty. Gophercloud endpoint resolution requires a region, so building EndpointOpts for the Swift service (or any requested service) aborts with the section name for localization.
