Set-Cookie header not being sent

Question

I am learning how to handle cookies with node.js and express and I encountered a rather peculiar problem. My cookie.js file looks like this:

var router = require('express').Router();

router.get('/cookie/', function(req, res) {
    res.append('Set-Cookie', 'foo=bar').cookie('hi', 'hello').status(200).json([]);
});

module.exports = router;

The problem is that the server is not sending the Set-Cookie header. However, if I modify Set-Cookie to Set-Cookiie then the header is sent (albeit not as a cookie).

I also tried to use res.cookie('hi', 'hello') after requiring and using CookieParser in my server.js and no cookie header is being sent. Why is this happening? Are any other packages (I have a few other packages) interfering with my headers?

Additional Information: I have HTTP running at :80 at HTTPS at :443 (self-signed) and the cookie problem persists in both connections.

I believe that with Postman in order to catch cookies and sessions , you have to install a little add-on Postman Interceptor :
