) -> Agent:
    return Agent(

        agent_id="police-agent",
        model=Gemini(
            id="gemini-1.5-flash",
            api_key=os.environ["GOOGLE_API_KEY"]

i think its fix after updating to latest phidata, the only problem is on agent api example, user must manually updating requirements to get latest phidata on exiting project
