Example Code

from langgraph.pregel.remote import RemoteGraph
import uuid
from langchain_core.runnables import RunnableConfig

graph=RemoteGraph(agent_name, url=get_config().lg.url)

config:RunnableConfig = {"run_id": uuid.uuid4()}

graph.ainvoke({}, config)

Error Message and Stack Trace (if applicable)

Description

I am using Langgraph RemoteGraph to execute my graphs registered on LangGraph Platform.
I wanted to use custom run ids, so I followed this documentation.
Custom Run Id

But, it did not work. Upon further debugging, I found that RemoteGraph sanitizes RunnableConfig during which it drops run_id and run_name fields.

Sanitization Code

It seems to be fully compatible, RemoteGraph should allow the same functionalities.
