Note : CORS error


Access to fetch at ‘https://a***.callidusondemand.com/api/v2' from origin ‘http://localhost:8080' has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

 




So… What is CORS?


CORS stands for Cross-Origin Resource Sharing and this is the definition according to MDN:




… is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources.


What this means in plain english is that CORS is a safety mechanism that requires browsers to deny access to a server other than the original server of the request.
