[BUG]: browser-use does not work with aiq serve

[alexliap]

Version

1.1.0

Which installation method(s) does this occur on?

Pip

Describe the bug.

I have added an extra graph before the 2 existing ones, which makes use of the browser-use library. The graph has only one node and uses the simple function below:

async def auto_browser_use(state: AIRAState, config: RunnableConfig):
    objective = config["configurable"].get("objective")
    browsing_llm = config["configurable"].get("browsing_llm")
    page_extraction_llm = config["configurable"].get("page_extraction_llm")

    agent = Agent(
        task=f"Objective:\n{objective}",
        llm=ChatOpenAI(
            model=browsing_llm,
            temperature=1,
        ),
        page_extraction_llm=ChatOpenAI(
            model=page_extraction_llm, temperature=0,
        ),
        browser_profile=BrowserProfile(headless=False),
        override_system_message=auto_browser_intruction,
        max_actions_per_step=8,
    )
    history = await agent.run(max_steps=25)
    contents = history.extracted_content()
    final_result = history.final_result()

    browser_use_results = """
    Browser Extracted content:
    {content}

    Final Result:
    {final_results}
    """

    return {
        "browser_use_results": browser_use_results.format(
            content="\n".join(contents), final_results=final_result
        )
    }

When the workflow is used with aiq run command it is running fine, it begins browsing and everything.
But when i am trying to host it with aiq serve the browsing capability stops and i get this error:

Given I dont have access to the aiq serve script i cant debug or change anything in its configuration.
I have tried hosting a tool with browser-use, with version0.1.48, before with fastapi and it works.
I cant use this version though because of the aira's dependencies.

Minimum reproducible example
