Issue with cloud front and CORS

Hi there, I’m getting this error for some agents using a custom app and not for others.

The call is coming from a Freshdesk modal which contains the Sendbird Calls library.

Access to fetch at '' from origin '' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

The domain is in the whitelisted list in the manifest. But as mentioned, it isn’t a problem for some agents but is for others.

Do you have any suggestions for what might cause this issue, please?
