WM8 upgrade - [ISC.0082.9026] Undefined Object found
We just upgraded to 8.0 from 7.1 IS.
A flow service is working different in 8.
In 8, the flow service returns an error failed: '/xxx VV-002 [ISC.0082.9026] Undefined Object found'
Where xxx is data in the pipeline but not defined in the flow service input.
The service did not do this under 7.1.
Input to the service has "Validate input" checked. The service is invoked from another service. The required input is provided, but its the other data in the pipeline that causes the error.
The solution is to create a new flow service, copy in the old implementation, delete the old implementation, and then rename the new service back to the old service name.
It seems new services created in 8 are fine, but services imported from 7.x show this bug.
