[SOLVED] Django-Reactjs : No Access-Control-Allow-Origin header is present on the requested resource

I'm trying to load an image from an image url and try to crop that image.

Access to image at 'https://example.com/image.png' from origin 'http://127.0.0.1:8000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I'm using React and Django.

app.js

import { useState,useCallback,useRef, useEffect} from 'react';
import React, { Component } from "react";
import ReactCrop from "react-image-crop";
import 'react-image-crop/dist/ReactCrop.css'

function App() {
 const [crop, setCrop] = useState({ aspect: 1.7777777777777777,
  height: 84.92083740234375,
  unit: "px",
  width: 325.97037760416663,
  x: 0,
  y: 140.07916259765625}
  );

 function onImageLoad() {
     const image = new Image();
      image.src =  "https://example.com/image.png";
      image.crossOrigin = "Anonymous";
     
    const canvas = document.createElement('canvas');
    

    const scaleX = image.naturalWidth / image.width;
    const scaleY = image.naturalHeight / image.height;
    const ctx = canvas.getContext('2d');
    const pixelRatio = window.devicePixelRatio;

    canvas.width = crop.width * pixelRatio * scaleX;
    canvas.height = crop.height * pixelRatio * scaleY;

    ctx.setTransform(pixelRatio, 0, 0, pixelRatio, 0, 0);
    ctx.imageSmoothingQuality = 'high';

    image.onload = function() {
  ctx.drawImage(
      image,
      crop.x * scaleX,
      crop.y * scaleY,
      crop.width * scaleX,
      crop.height * scaleY,
      0,
      0,
      crop.width * scaleX,
      crop.height * scaleY
    );
    }

 const base64Image = canvas.toDataURL("image/jpeg", 1);
            setResult(base64Image);
            console.log(result);
  }

    useEffect(() => {
    onImageLoad();
 
   
  }, []);

return ( 
   {
                result &&
                <div>
                    <h2>Cropped Image</h2>
                    <img
                        alt="Cropped Image"
                        src={result}
                        crossorigin="anonymous"
                         style={{
                      width: Math.round(crop?.width ?? 0),
                      height: Math.round(crop?.height ?? 0)
          }}
                    />
                </div>
            }
)

}
