AEM - Salesforce lightning component - Access-Control-Allow-Origin

When I try to access salesforce lightning components in AEM, I was not able to access the lightning script from AEM server, I got below error in browser console.


XMLHttpRequest cannot load 
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' 
header is present on the requested resource. Origin 'https://localhost:5544' is therefore not allowed access.


We need to whitelist the origin i.e. our aem server in salesforce. 
  • Goto site, click on Setup -> search for CORS
  • Goto CORS console, give the AEM server url pattern, in my case it is https://localhost:5544
