Hi,
So I'm trying to turn this Nginx-ingress definition to a Traefik-ingress definition and It doesn't work properly. Nginx-ingress file uses regex for different paths. So I created middlewares in Traefik to simulate the behaviour but no luck. As an example, /swagger-ui/ path with traefik ingress will always redirect to /home.
I paste here both definitions in order to make it clear.
nginx-ingress definition:
apiVersion: networking.k8s.io/v1
kind: Ingress

Has anyone any idea why it does the redirect?
P.S: Sorry for copying the whole config file.
