Has anyone done any testing with SuiteScript 2.1 trying to load a sales order and I get the following exception execute on foreign object failed due to: UnsupportedTypeException. If I go back to 2.0 record loads no issue. Same thing happens for work order, and customer

Hi @JohnnyC this is a known defect currently in the process of being resolved. You can refer to Defect 578832 if you would like to log a support case so that you are notified when the fix is out. It should be just a couple of days.

Thanks for the info.
