    {Object.keys(gifs).length === 0 ? (<div>loading...</div>):<div className='gif-section'>
        {gifs.data.map((items)=>{
           return(
               <a href="#" className='image-gifs' key= {items.id}>
               <img className="live-gifs" onClick= {()=>getGifId(items.id)} src= 
                 {items.images.fixed_height.url} alt="..."/>
               </a>
               )
            })
         }
      </div>
     }
</>

What I have tried:

import axios from "axios";
import { useState } from "react";
import { useEffect } from "react";

 
const GifInText = ({gifId}) => {

    const [post, setPost] = useState({})
    console.log("post:",post );

    const fetchData = async () =>{
           axios.get(`https://api.giphy.com/v1/gifs/${gifId}`,{
                params: { 
                    api_key: "Xoa3mXrWxKXw6lJscrKUTsbZsXLbGuGY",
                    gif_id: gifId
                }
            }).catch((error) =>{
                console.log("error at fetching gifID2", error);
              }).then(response => {
                setPost(response.data)
              });
            }
    useEffect(()=>{
        fetchData()
        }, [ ])

        return (
            <div>         
                {
                  Object.values(post).length && Object.values(post).map((items)=>{
                        return(
                            <>
                            <h1>{items.id}</h1>
                            <img className="live-gifs" src={items.images.fixed_height.url} 
                             alt="..."/>
                            </>
                        )
                    })
                }           
            </div> 
         )
}
export default GifInText;
