Hey, could you please share the imports you’re currently using along with the SDK version?

#

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI
from composio_langchain import ComposioToolSet, App, Action
from langchain_core.messages import SystemMessage, HumanMessage
from datetime import datetime

let me figure out my sdk version

#

composio-0.1.1.dist-info
composio_langchain-0.7.20.dist-info
composio_core-0.7.20.dist-info

#

should I swap to the newer composio?

We’ll attempt to reproduce the issue on our end and update you. Yes, switching to version 3 is recommended as it’s more reliable for frameworks like Langchain.
