I'm experiencing CORS issue with Chat Widget V2. I copied the sample code given in the link below and updated with widget API link and other details but I see CORS issue. I tried both localhost and deployed in DEV server, in both i see same CORS issue - issue happening in Chrome and Edge browser.
Your config looks correct to me. It looks like there's a bug in Genesys Cloud relating to serving those files correctly. Please open a case with Genesys Cloud Care to investigate the bug further.
