Hey, has there been any updates towards guardrails support ?, I remember there was a couple of issues when integrating guardrails, llamaindex, langchain together in one

I'm facing an issue with query_engine.query(), the error output is quite long so I've put it here with the minimal code that resulted in the issue.

Could it be a python version issue?
tested in a new venv on LlamaIndex v0.8.14 on python 3.11.4

Another note, this error does not show up when providing an llm to StructuredLLMPredictor(llm=my_llm)
