CORS Error Heroku hosted ReactApp

Hi Ashhok,

you will need to properly fill ingress.annotations as described in this article. Please check the chart example below:

ingress:
  ...
  # Custom annotations that will be added to every Ingress object created by this chart, e.g.
  # cert-manager.io/cluster-issuer: letsencrypt-production
  # If you plan to do local development of GoodData.UI applications, you should also add
  # CORS-related annotations like:
  # nginx.ingress.kubernetes.io/enable-cors: "true"
  # nginx.ingress.kubernetes.io/cors-allow-headers: "X-GDC-JS-SDK-COMP, X-GDC-JS-SDK-COMP-PROPS, X-GDC-JS-PACKAGE, X-GDC-JS-PACKAGE-VERSION, x-requested-with, X-GDC-VALIDATE-RELATIONS, DNT, X-CustomHeader, Keep-Alive, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, Authorization"
  # nginx.ingress.kubernetes.io/cors-allow-origin: http://localhost:3000
  annotations: {}

Hello @ashok,

Updating to GoodData.CN version 1.4 shouldn’t have any effect on CORS. I learned from our Dev teams that we upgraded Kubernetes which caused one annotation to change (kubernetes.io/ingress.class: nginx), but this has nothing to do with CORS. If it worked before, please make sure that you are correctly replicating the same settings for CORS allowed origins in version 1.4, there shouldn’t be a difference!
