Describe the bug Hi Team,

I was trying out the new tracing feature with LangChain. I can see the input and output are traced as NULL.

How To Reproduce the bug Steps to reproduce the behavior, how frequent can you experience the bug:

Just run the code end to end https://github.com/microsoft/promptflow/blob/43a33638faaca31ddc5231192f722a31dfd9a109/examples/tutorials/tracing/langchain/trace-langchain.ipynb

Expected behavior It should capture both input and output
