Hi Pavol, Thanks for your reply! I also tried with port 8080, but the issue is still there. [cors_error_public] Regarding whitelist, I was already aware of it, so, anytime I use ShapeDiver API, I added the domain name with/without port number in the list. So, it does not help this issue neither. …

You don’t need any extensions to embed ShapeDiver models successfully. Can you double-check that: You set up the global domains correctly You enabled them in model settings We allow port 8080 for local testing and it should just work. Could you give me more details what are you trying to do? Link…
