Hi , I got this error when running the subquestion query engine, i tried to debug on my own but it seems like the global_stack_trace became empty after the first subquestion query was completed. No idea how to go about fixing it.
Traceback (most recent call last): File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/indices/query/base.py", line 23, in query response = self._query(str_or_query_bundle) File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/query_engine/sub_question_query_engine.py", line 142, in _query qa_pairs_all = [ File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/query_engine/sub_question_query_engine.py", line 143, in <listcomp> self._query_subq(sub_q, color=colors[str(ind)]) File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/query_engine/sub_question_query_engine.py", line 238, in _query_subq with self.callback_manager.event( File "/opt/conda/envs/xxx/lib/python3.10/contextlib.py", line 135, in enter return next(self.gen) File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/callbacks/base.py", line 169, in event event.on_start(payload=payload) File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/callbacks/base.py", line 242, in on_start self._callback_manager.on_event_start( File "/opt/conda/envs/xxx/lib/python3.10/site-packages/llama_index/callbacks/base.py", line 105, in on_event_start parent_id = global_stack_trace.get()[-1] IndexError: list index out of range
