I was trying to fetch the news api but I kept on geeting this errors "" TypeError: Cannot read properties of undefined (reading 'map') "" is there any syntax or I need to add something

 import React, { Component } from 'react'
   import NewsItem from './NewsItem'
   export default class News extends Component {
   constructor(){
   super();
   this.state={
       article : this.article
       }
   }

       async componentDidMount(){
       let urll = "https://newsapi.org/v2/top-headlines? 
        country=in&apiKey=6aeca0faebbd45c1a1ec3c463f703ebb";
       let data = await fetch(urll); 
       console.log(data)
       let parseData = await data.json() ; 
       console.log(parseData);
       this.setState({article : parseData.articles});
      }

        render() {
        return (
         <div className='newcontainer my-5'>
         <h1 className='mainheading' >PAHADI PRESS BREAKING NEWS</h1>
         {this.state.article.map((e)=>{
          return <div key={e.url} >
           <NewsItem  title={e.title} decription={e.description} imageUrl={e.urlToImage} 
           newsUrl={e.url}

         </div>
       })
     }
     </div>
     )
     }
     }
