Axios get access to response header fields

Question

I'm building a frontend app with React and Redux and I'm using axios to perform my requests. I would like to get access to all the fields in the header of the response. In my browser I can inspect the header and I can see that all the fields that I need are present(such as token, uid, etc...), but when I call

const request = axios.post(`${ROOT_URL}/auth/sign_in`, props);
request.then((response)=>{
  console.log(response.headers);
});

I get just

Object {content-type: "application/json; charset=utf-8", cache-control: "max-age=0, private, must-revalidate"}

Here my browser network tab,as you can see all the other fields are present.

Bests.

In case of CORS requests, browsers can only access the following response headers by default:

• Cache-Control
• Content-Language
• Content-Type
• Expires
• Last-Modified
• Pragma

If you would like your client app to be able to access other headers, you need to set the Access-Control-Expose-Headers header on the server:

Access-Control-Expose-Headers: Access-Token, Uid
