Unable to read response object on react

My django api responds with the username if the user is authenticated and a not authenticated details msg if not authenticated, but I am unable to read the status code or console log or catch the 401 status code and res.status gives undefined msg:

console img

How can I use http status to render depending on the code received?

export default class GetUser extends Component {.....}  componentDidMount(){    fetch("http://127.0.0.1:8000/app/ebooks/",    { CSRF_TOKEN.....      },     })     .then(res => res.json())    .then(res => {       this.setState({data:[res]})      console.log(resp.status)  ---> UNDEFINED    })    .catch(err => console.log(err));  }  render() {    var x = this.state.data      return (<pre>{JSON.stringify(x, null, 2) }</pre>    )  }}
