Hello,
I get the below error message :
Access to XMLHttpRequest at '{CA Proxy location}' from origin {Client UI location } has been blocked by CORS policy : The 'Access-Control-Allow-Origin' header contains multiple values '*, {Client UI location }, but only one is allowed.
In the Process CORS Request properties assertion, Accepted Origins tab has 'Allow All' option selected.
I couldn't find any other location where it might have got added twice.
Please suggest.
