In React Js Axios request getting CROS error

I used Axios for API, here is my code. I am getting CROS error.

axios({
      method: 'GET',
      headers : { 'Content-Type': 'application/json',
                  'Access-Control-Allow-Origin' : '*',
                  'mode': 'cors',
                  'Authorization':'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1N....'
                },
      url: baseURL,          
    }).then(function (response) {
          console.log(response);
    });
