Error while adding the individual action plan to a case and escalating HRHD to a case

Summary:

Receiving error message JBO-FND:::FND_CMN_INVALID_ATTRB_API_SERV: (SVC-5295310) in two case management scenarios.

1. Adding an individual action to a case. The same action works when added through Action Plan Template.

2. Escalating an HRHD to a case, even after action and VBS mapping.

Any guidance, documentation references, or implementation examples would be greatly appreciated.

Thank you.
