OPTIONS http method and CORS is not enabled. Set icf/cors_enabled in RZ11

What causes this issue?

The BW http handler for INA requests has received an OPTIONS http
request. This should not reach the BW http handler but be handled above
by the ICM (internet connection manager). Usually this is because CORS
was not correctly configured.

System Response

Error is raised in the http handler class
