Events get forbidden status on Kubernetes

I managed to solve it using Istio. In case anyone using Istio and running into this problem, I used this VirtualService:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: sentry-web
  namespace: sentry
spec:
  hosts:
  - "mydomain"
  gateways:
  - 'my-gateway'
  http:
  - match:
    - uri:
        exact: /api/store/
    route:
    - destination:
        port:
          number: 3000
        host: sentry-relay
  - match:
    - uri:
        regex: .*/api/.*
    route:
    - destination:
        port:
          number: 3000
        host: sentry-relay
  - route:
    - destination:
        port:
          number: 9000
        host: sentry-web
