401 response code is shown as 200

var nodeFetch = require("node-fetch")
nodeFetch('https://bitbucket.org/atlassian/foo/get/master.zip').then((res) => {
  console.log(res.status);
});

This URL returns 401 but for some reason, I get back 200.

I will be closing this as it seems like a misunderstanding of server behavior.

@1999 that zip url requires authentication. So when you try to access it without any auth info it will redirect you to a login page. The login page is returning the successful 200. Curl wont follow redirects with just the curl command. The -L flag should make curl follow the redirect and return a 200. 3xx codes indicate a redirection. fetch defaults to follow the redirects which is why without that param it is returning a 200.
