since I could not find anything in Google or in the Duet Enterprise Troubleshooting Guidelines I post my problem here.
I configured the Workflow functionality, but do not receive any workflow tasks in SharePoint. On the SCL logs I see that the SCL received the task (method Recv-item is green) but the following error message is raised in method Proc_item:
An error has occured in the XML transformation of WorkflowContainerElements
After this error message I get the following additional errors (still in the same method):
The processing of the request failed permanently
Error when reading object with ID ''
Failed to read SCL Business Object 'IW_WF_TASK' '' ''
Thanks for your help!
