Error :

Access to fetch "private url" from origin ' been blocked by CORS policy: Response to preflight request doesn't pass access control check: No Access-Control-Allow-Origin' header is present on the requested resource.

And gateway timeout.

The backend is of node js and deployed on azure app service which uses azure application gateway.

I tried changing the service worker configuration many times as suggested many articles. But none hepled me out.

After everything i could try i came accros this subreddit.

"I do not have permissions to change anything on app service or gateway"
