I had the same issue, and i have fixed by adding CorsFilter bean

  @Bean
  public FilterRegistrationBean corsFilter() {
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(true);
    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("*");
    source.registerCorsConfiguration("/**", config);
    FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
    bean.setOrder(0);
    return bean;
  }

And adding zuul's properties this code

zuul:
  sensitiveHeaders:
  ignored-headers: Access-Control-Allow-Credentials, Access-Control-Allow-Origin
