can not set recursion_limit in config with langserve

Checked other resources

• [X] I added a very descriptive title to this issue.
• [X] I searched the LangChain documentation with the integrated search.
• [X] I used the GitHub search to find a similar question and didn't find it.
• [X] I am sure that this is a bug in LangChain rather than my code.

Example Code

I create a graph with langserve.

workflow = StateGraph(PlanExecute)
.... add the nodes and edges...
c =  workflow.compile()

.....
app = FastAPI(
    title="AI Agent Sever",
    version="0.2.9",
    description="AI Agent Sever"
)
add_routes(
    app,
    c,
    path="/pe"
)

when I use following request invoke. I found the "recursion_limit" parameter config not used.

{
    "input": {
        "transaction": "xxxxxxxx.",
        "conversation_id": ""
    },
    "config": {
        "configurable": {
            "recursion_limit": 2
        }
    }
}

Recursion limit should be top level, rather than nested within configurable

Seems this is resolved? Will mark as closed unless others run into this.
