Zuul and Consul integration issue - spring

Question

I have problem setting up Spring Cloud application with Zuul and Consul service discovery. I have Consul server agent installed and running locally:
./src/main/bash/local_run_consul.sh
When I run Spring Boot application with #EnableZuulProxy annotation I get the following error:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.netflix.zuul.filters.RouteLocator]: Factory method 'routeLocator' threw exception; nested exception is java.lang.IllegalStateException: Unable to locate service in consul agent: edge-server-8765

#EnableZuulProxy
public class ZuulApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(ZuulApplication.class).web(true).run(args);
}
}
Note: When I comment out the #EnableZuulProxy annotation, my service runs without problems and is registered in Consul correctly.
I have no idea what to do. Maybe there is some bad dependency issue?
Thanks in advance.

There is a bug in spring-cloud-consul with ConsulDiscoveryClient.getLocalServiceInstance.
Setting zuul.ignoreLocalService: false will work around it for now.
