The default option for signature_type was set to 'required' which UPS started rejecting for services and rating sometime in mid June 2022.
The error messages returned were not terribly clear on what the actual issue was:
Code: Client
An exception has been raised as a result of client data.
Code: 111211
The requested accessory option is unavailable between the selected locations.
The fix is to set the signature_type to 'not_required'
