Getting CORS issue 

I am getting a CORS issue as below when trying to run the front end 

Access to XMLHttpRequest at 'http://gateway-vertx-undefined.localhost/api/products' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I tried few options as suggested on stackoverflow and all but no luck.
