Example Code (Python)

from dataclasses import dataclass

from langchain.agents import create_agent


@dataclass
class Context:
    user_id: str
    session_id: str

agent = create_agent(
    model=model,
    tools=tools,
    context_schema=Context  
)

result = agent.invoke(
    {"messages": [{"role": "user", "content": "Hello"}]},
    context=Context(user_id="123", session_id="abc")  
)

Error Message and Stack Trace (if applicable)

Description

Runtime context is not supported now?

The context_schema and context parameters doesn't exist.

for create_agent(), action_agent.astream(), action_agent.ainvoke(), ChatOpenAI(), model.ainvoke() and so on.

The old config["configurable"] pattern still works for backward compatibility,
but using the new context parameter is recommended for new applications
or applications migrating to v1.
