We have an option of creating a case through data flow, by choosing Destination as Case, then passing the case type in the drop down.
I can no longer see my case type in this drop down. Upon analyzing the issue, I realized the list of case types on the properties of destination shape is populated by D_StartingFlowsAsList data page. This data page is looking for an instance of Data-Admin-StartingFlows class.
Since 8.5, pega no longer creates an instance of Data-Admin-StartingFlows class while creating a new case type as explained in this link.
