HI team, I'm trying to retrieve the source nodes and node ids from the sub questions in the sub question query engine, i see that this notebook shows how to get the sub query questions but what about the source nodes for those questions?
ok was able to recreate it in a simple version {'qa_pair': 'sub_q=SubQuestion(sub_question="What is the patient's medical history?", tool_name='use_this') answer=None sources=None'}]
