Langchain & Langsmith Integration fails

We've integrated Langchain in our convex app and it's working great.

But we can't get Langchain tracing to work at all. It simply does nothing on the convex backend. No errors. No logs. No traces on Langsmith. Nothing.

We've integrated following these docs:
https://docs.smith.langchain.com/observability/how_to_guides/tracing/trace_with_langchain

All the env vars are set in the Convex dashboard including the LANGCHAIN_CALLBACKS_BACKGROUND=false

But still no traces. No logs. No errors anywhere.

Ideas?
Trace with LangChain (Python and JS/TS) | 🦜️🛠️ LangSmith
LangSmith integrates seamlessly with LangChain (Python and JS), the popular open-source framework for building LLM applications.

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
