Issue with case type in Pega 7.4

Data model(Data Transform-PyDefault class) is missing, not getting created while creating a case type in Pega 7.4. Could anyone suggest

the solution and kindly let me know what might be the issue.

Hello @sreesathyac

In the pyStartCase flow, we invoke this pyDefault Data Transform while case creation. You can take look at screenshots and as well in your application. Check whether this DT is there or not, I think the DT has been removed or blocked somehow. Refer below links.
