Symptoms

In a SmartObject event we are trying to execute a SmartObject method (list method with input parameters) and assign the return property to a Workflow Data field.

However, the process finishes in error status even if everything seems to be ok.

 

Diagnoses

It seems there is something wrong with the SmartObject, or some other backend changes were made that don't reflect in the SmartObject.
 

Resolution

After changing the SQL column data type from decimal to integer and regenerating the SmartObject, it seems to be working.
