Redirect from www to non www duplicates query params kubernetes - kubernetes

Question

I am trying to redirect from https://example.nl to https://www.example.nl. This works perfectly. However, when I add query params, the query params get duplicated.
For example, whenever I go to example.nl?test=a, it redirects to wwww.example.nl?test=a?test=a.
How do I prevent this duplication of query params?
I use kubernetes and digital ocean. My kubernetes ingress file looks as follows:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: app-ingress
annotations:
service.beta.kubernetes.io/do-loadbalancer-name: "example"
kubernetes.io/ingress.class: nginx
cert-manager.io/cluster-issuer: letsencrypt-prod
nginx.ingress.kubernetes.io/backend-protocol: HTTP
nginx.ingress.kubernetes.io/configuration-snippet: |
if ($host = 'example.nl' ) {
rewrite ^ https://www.example.nl$request_uri permanent;
}

try something like
annotations:

rewrite / https://test.app.example.com$uri permanent;
