I have an application named metadata running in EKS, which serves traffic on /api. The service of metadata configuration is as follows:

Service Configuration:

spec:
  ports:
  - name: web
    port: 80
    protocol: TCP
    targetPort: 8080
  selector:
    app: metadata
  type: ClusterIP

This application has Swagger configured, and I am using Istio as the ingress controller. I have created a VirtualService for this service as shown below:

VirtualService Configuration:

- match:
  - uri:
      prefix: "/metadata/"
  - uri:
      prefix: "/metadata"
  rewrite:
    uri: "/"
  route:
  - destination:
      host: metadata.core.svc.cluster.local
      port:
        number: 80

The desired URL should be like: https://example.com/metadata/, and Istio should rewrite this and route to the pod on /api.

This works as expected when I use Traefik as the ingress controller. However, with Istio, I am facing an issue. When accessing the Swagger UI URL in the browser at https://example.com/metadata/swagger-ui, it works initially. But when I try to test some API from the UI, it trims the base path and creates the request URL as https://example.com/api/request instead of https://example.com/metadata/api/request.

Note: Its working when i try the same test with curl command.

My issue is similar to this question, but I do not want to change my code because the same code is used in other environments where Traefik is the controller.
