This is the schema

 I am giving {fetchedData.image} as src of img

Images exist as references to an image asset in Sanity, so you need to expand the reference in order to get the url. There's a good introduction to presenting images here .

import React, { useEffect, useState, useLayoutEffect } from 'react';

import { Link } from "react-router-dom";

import Header from "../components/Header";

import "./Home.css";

import {Carousel, Card, Image} from 'antd';

import {client} from "../lib/client";



const Home = () => {

const [products,setProducts]= useState([]);

const [bannerData,setBannerData]= useState([])


useEffect(() => {
`client.fetch(
*[_type == "featured"]{

name,

genre,

image

}
).then((data)=>setProducts(data))` 
}, [])


useLayoutEffect(() => {
`client.fetch(
*[_type == "banner"]{

image

}
).then((data)=>setBannerData(data))` 
}, [])


return(

<>

<div className="container">

<Header/>

<Carousel autoplay className="carousel">

{bannerData?.map((data) => {

return <img src={urlFor(data.image).url()} className="carousel-img" alt="carousel"></img>;

})}

</Carousel>

<div className="cards">

{products.map((product)=>{

return(

<Card className="card" key={product._id}>

<Link to="/categories" state={product.genre} className="link" style={{textDecoration:"none"}}>

<img src={urlFor(product.image).url()} alt={product.name} className="card-content"/>

<h4>{product.name}</h4>

</Link>

dataset:'production',

apiVersion:'2022-03-10',

Please help anyone

You'll need to import your 
urlFor
function wherever you want to use it, then pass your image asset to the function. It looks like you're doing that with your product image but not your banner data.

I am doing that in bannerData too and it says Uncaught (in promise) Error: Unable to resolve image URL from source ([{"_key":"c86fb91a8ad3","_type":"image","asset":{"_ref":"image-48f1b8fa7db78f55843dcd58547080123dc36adb-192x293-webp","_type":"reference"}}])
May 16, 2022, 7:00 PM
Can you try passing in the asset instead of the entire image?
May 16, 2022, 7:01 PM
What does it mean to pass the asset?image.asset?
May 16, 2022, 7:02 PM
Yes
May 16, 2022, 7:03 PM
Now it says Uncaught (in promise) Error: Unable to resolve image URL from source (undefined) at urlForImage (urlForImage.ts
:43:1) at ImageUrlBuilder.url (builder.ts
:229:1) at Home.js
:42:1 at Array.map (&lt;anonymous&gt;)
at Home (Home.js
:37:1) at renderWithHooks (react-dom.development.js
:14985:1) at updateFunctionComponent (react-dom.development.js

Strangely the docs says passing the image is enough
May 16, 2022, 7:05 PM
Now you can use this handy builder-syntax to create your URLs:
<img src={urlFor(person.image).width(200).invert().flipHorizontal().url()} />

May 16, 2022, 7:06 PM
This is what documentation says
May 16, 2022, 7:06 PM
Now i tried this <img src={urlFor(`<https://cdn.sanity.io/images/uykjgyz0/production/${data.image.asset._ref.slice(6)}>`).url()}
May 16, 2022, 7:26 PM
Still doesn't work
