    Simple example integrating with Tracer

    from aws_lambda_powertools.event_handler import VPCLatticeResolver

    tracer = Tracer()
    app = VPCLatticeResolver()

    @app.get("/get-call")
    def simple_get():
        return {"message": "Foo"}

    @app.post("/post-call")
    def simple_post():
        post_data: dict = app.current_event.json_body
        return {"message": post_data}
