How about I was wondering if someone has resolved the CORS issue for http-s requests

I mark an error like this below…

from origin ‘[http://localhost:3000](http://localhost:3000/)’ has been blocked by CORS policy: The value of the ‘Access-Control-Allow-Origin’ header in the response must not be the wildcard

Is it due to web development issues in this case on the fronted side?
