cors issue with fetch api

Question

I am calling an API with isomorphic-fetch with Fetch API. I was getting CORS issue as API was on different domain (this works in production).

To develop locally, I ran chrome browser in non-secure mode and added { credentials: "include" } as part of request headers so that cookies will be sent along with request.

my dev domain is localhost.abc.com:8080 and api is on myapi.abc.com, although i am getting 200 OK response, i am unable to read the response because of below error:

The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'

This is where I have started missing jQuery AJAX call in relation to the Fetch API.

Could you reduce your test case by eliminating the isomorphic-fetch and update your question? This can probably be reproduced using window.fetch in the dev console. Also, please provide an example of how you would accomplish your goal with jQuery.ajax. Thanks. — vhs

Try setting Access-Control-Allow-Origin to specific domain you want to whitelist, eg. localhost.abc.com:8080 in your case.
