I am designing to create a service in PEGA, which allows external systems to create separate cases. When I use the Service Wizard, I am selecting the "Create and Manage work" option and creating a service rule of type SOAP. To enable the case creation, I am selecting the flow type pyStartCase

When I run my service, I can generate the case, creating the instance, however, on return of service comes the following message:

<pyAssignmentList>
<pyAssignedTo>BrokenProcesses</pyAssignedTo>
<pyAssignmentClass>Assign-WorkBasket</pyAssignmentClass>
<pyAssignmentHandle>ASSIGN-WORKBASKET BS-FW-CALCULOPREMIO-WORK POC-3!FLOWPROBLEMS</pyAssignmentHandle>
<pyFlowType>FlowProblems</pyFlowType>
<pyInstructions>Repair flow configuration</pyInstructions>
</pyAssignmentList>
<pyAssignmentList>
<pyAssignedTo>default@</pyAssignedTo>
<pyAssignmentClass>Assign-Internal</pyAssignmentClass>
<pyAssignmentHandle>ASSIGN-INTERNAL BS-FW-CALCULOPREMIO-WORK POC-3!PZINTERNALCASEFLOW</pyAssignmentHandle>
<pyFlowType>pzInternalCaseFlow</pyFlowType>
<pyInstructions/>

What default fields must be present in the service structure, so that a Flow Problem is not generated. Or rather, should I tweak the configuration of pyStartCase, allowing it to configure the desired routing?

Thanks !
