Hi,

We encountered an issue after upgrading to Pega 24.1 when attempting to create a case. In the tracer, we noticed an activity called CreateWorkPage, where the error occurs at Step 11: Apply-DataTransform, which passes the parameter ModelToUse. Upon reviewing the parameter page, we found that Param.ModelToUse is set to "pyDefault".

The issue only occurs on the first attempt. However, if we reload the page and try again, the case is created successfully without any errors.

Below is the full error message from the tracer:

Failed to find a 'RULE-OBJ-CASETYPE' with the name 'PYDEFAULT' that applies to '@baseclass'. There were 104 rules with this name in the rulebase, but none matched this request. The 104 rules named 'PYDEFAULT' defined in the rulebase are: 104 related to applies-to class '@baseclass', but were defined on subclasses: {Class X, X, etc}.

Has anyone encountered a similar issue before? If so, could you share any insights or possible solutions?

Thank you!
