How do I solve this firebase functions cors error?

Question

I am trying to make stripe payments via firebase functions but I keep getting this Access to fetch at ‘my firebase functions link’ from origin ‘localhost:8000’ has been blocked by CORS policy : No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s node to ‘no-cors’ to fetch the CORS disabled
