yes, correct

Not another tracing instrumentation, but I had another callback registered with Langgraph. I tried disabling it - still the same issue,

I ask, because one thing that could cause this would be multiple instrumentation packages in your environment that are both attempting to instrument your LLM calls

Let me check this

4 Traces for a single graph run. Main Langgraph trace has multiple spans for different graph nodes. Couple of these graph nodes make LLM /Tool calls. And these are shown as 3 separate traces. When I expand the Langgraph trace, I don't see any LLM invocation span within it.

No. not seeing the LLM spans within Langgraph trace. Let me see if I can share a quick screenshot

I am using ChatOpenAI model from langchain.

I see LLM and Langgraph as two separate trace hierarchy for a single run

In my exanple, I am not doing the bind_tools on chat model because I am implementing ReWoo. So, I understand if tools are not part of the same trace. But not understanding why Chat Model invocations are not part of the same trace.

can you point me to that base langgraph example where it is working ? I can try to reproduce and see if I am doing anything different ?

No, I have a custom graph. But when it was not working, I did come across that. I didn't see anything different being done in that notebook as far as instrumentaion is concerned ?
