Solutions

1. Verify the memory_id exists before the operation.
2. List memories and use a valid id; the record may have been deleted.

Example fix

mem = MemoryService.get_by_id(memory_id)
if not mem:
    raise ValueError(f"Memory '{memory_id}' not found.")

When it happens

Trigger: Thrown at api/apps/services/memory_api_service.py:297 when the library encounters an invalid state.

Common situations: The request references a memory id that does not exist or was deleted; confirming the id beforehand prevents this error.
