Showing double Animation on web page

Lottie in Web
1

I used this code in Nextjs and it showing 2 instances of animation.

const container = useRef(null);

useEffect(() =>{
    lottie.loadAnimation({
      container: container.current,
      renderer: "svg",
      loop: true,
      autoplay: true,
      animationData: require("../../public/jsonanims/growBusiness.json"),
    });
    lottie.setSpeed(0.4);
}, [])
