Springdoc generated server url is http instead https on traefik reverse proxy

Question

Spring Boot 3.2.0 application with springdoc-openapi-ui runs on HTTP server port for proxy traefik. The application is deployed to Kubernetes with Ingress routing HTTPS requests from outside the cluster to the service.

In this case Swagger UI available at https://example.com/swagger-ui/index.html has wrong "Generated server url" - http://example.com/. While it should be https://example.com/.

While Swagger UI is accessed by HTTPS, the generated server URL still uses HTTP.

apiVersion: traefik.containo.us/v1alpha1

    {{- else }}
    - match: Host(`events.sea.{{ .Values.environment }}.cloud.example.com`) && {{ .Values.INGRESS_MATCH }}
    {{- end}}
