Issue: Traces not showing for LLM calls when using CrewAI

[othmansamih]

Issue you'd like to raise.

Description:

I am working on a project with CrewAI (built on top of LangChain) to implement agents. However, I encounter an issue where the traces of LLM calls are not displayed in LangSmith.

When I test a simple script using ChatOpenAI directly, as per LangSmith's documentation example, it works fine. For instance:

from langchain_openai import ChatOpenAI

llm = ChatOpenAI()
llm.invoke("Hello, world!")

However, when using CrewAI built-on top of Langchain Framework, no traces appear in LangSmith.

Here are the configurations in my .env file:

LANGCHAIN_TRACING_V2=true
LANGCHAIN_ENDPOINT="https://api.smith.langchain.com"
LANGCHAIN_API_KEY=<my-api-key>
LANGCHAIN_PROJECT="crewai-project"

Environment Details:

• python: 3.10.0
• crewAI: 0.86.0
• langChain: 0.3.13
• langChain-openai 0.2.14
