Эврика обнаружила, что служебный статический (угловой) контент не обслуживается через шлюз (spring-cloud-gateway)

У меня проблема, когда пользовательский интерфейс Angular 7 не обслуживается, когда маршрут вызывается через шлюз. 

Gateway service (gateway): http://localhost:8060 ---> Routes are located
UI Service (appui) : http://localhost:8091/ ----> This works
Routed URL: http://localhost:8060/appui ----> This does NOT work

Облако версий: Greenwich.SR1, boot: 2.1.5.RELEASE, angular:7

Маршруты автоматически расположены в шлюзе. 

 [{"route_id":"app_ui","route_object":{"predicate":"org.springframework.cloud.gateway.support.ServerWebExchangeUtils$$Lambda$388/0x0000000800442840@4b6ae744","filters":["OrderedGatewayFilter{delegate=org.springframework.cloud.gateway.filter.factory.StripPrefixGatewayFilterFactory$$Lambda$391/0x0000000800441840@50ab56e2,
order=0}","OrderedGatewayFilter{delegate=org.springframework.cloud.gateway.filter.factory.RewritePathGatewayFilterFactory$$Lambda$393/0x0000000800441040@7b5b5bfe,
order=0}"]},"order":0},{"route_id":"CompositeDiscoveryClient_APPUI","route_definition":{"id":"CompositeDiscoveryClient_APPUI","predicates":[{"name":"Path","args":{"pattern":"/appui/**"}}],"filters":[{"name":"RewritePath","args":{"regexp":"/appui/(?<remaining>.*)","replacement":"/${remaining}"}}],"uri":"lb://APPUI","order":0},"order":0},{"route_id":"CompositeDiscoveryClient_GATEWAY","route_definition":{"id":"CompositeDiscoveryClient_GATEWAY","predicates":[{"name":"Path","args":{"pattern":"/gateway/**"}}],"filters":[{"name":"RewritePath","args":{"regexp":"/gateway/(?<remaining>.*)","replacement":"/${remaining}"}}],"uri":"lb://GATEWAY","order":0},"order":0}]

В шлюзе я определил построитель маршрутов, чтобы добавить трейлинг / на маршрут пользовательского интерфейса.**** Примечание: это только последняя версия, я пробовал множество комбинаций. **

@Bean
    RouteLocator routes(final RouteLocatorBuilder routeBuilder) {
        return routeBuilder.routes()
                .route("app_ui",
                        route -> {
                            Route.AsyncBuilder uri = route
                                    .path("/appui/**")
                                    .filters(
                                            f -> f.stripPrefix(1).rewritePath("/appui/(?<RID>.*)", "/${RID}/")
                                    )
                                    .uri("http://localhost:8091");
                            System.out.println(uri);
                            return uri;
                        }
                )
                .build();
    }

Журналы шлюза ниже показывают, что маршрут использует службу пользовательского интерфейса, но возвращает сами файлы, ноне отображаемое содержимое:

My Gateway application.yml выглядит следующим образом: 

server:
  port: 8060

spring:
  application:
    name: gateway

  cloud:
    gateway:
      discovery:
        locator:
          enabled: true
          lowerCaseServiceId: true

eureka:
  client:
    fetch-registry: true
    register-with-eureka: true
    serviceUrl:
      defaultZone: http://localhost:8082/eureka
    healthcheck:
      enabled: true

management:
  endpoint:
    gateway:
      enabled: true

  endpoints:
    web:
      exposure:
        include: gateway

Мой пользовательский интерфейс application.yml: 

server:
  port: 8091

spring:
  application:
    name: appui

management:
  health:
    binders:
      enabled: true

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8082/eureka
    healthcheck:
      enabled: true

Может ли маршрут с балансировкой нагрузки повлиять на переписывание или добавление завершающего / для пользовательского интерфейса или это что-то еще?

Спасибо!

Пробовал переписывать маршруты, добавляя трейлинг /
