Understanding and Fixing CORS Error
CORS is implemented on the server-side; it cannot be reconfigured on the client-side. The CORS behavior, commonly termed as CORS error, is a mechanism to restrict users from accessing shared resources.
This is not an error but a security measure to secure users or the website which you are accessing from a potential security breach.
This breach may occur due to incomplete or improper HTTP headers on the client-side implementation (eg. missing authorization data such as API key).
