[null] java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING (Dynamic Script Module name : addCustomProperty#19)

Has anyone run into issues with the com.vmware.library.vcaccafe.businessgroup.addCustomProperties action with vCAC plugin (6.1) and vCO (5.5.2 appliance)?


In my test environment with the versions listed above I  keep getting the following error:


java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING (Dynamic Script Module name : addCustomProperty#19). 


It seems to fail at the "service.update(group)" call in the code.  According to the plugin API "group" is type vCACCAFE:BusinessGroup, thus the error of BEGIN_OBJECT but was STRING doesn't make sense to me. 


 


Thanks all,
