Overriding the zuul error error results in a forwarding error

Question

I am trying to override the default senderorfilter parameter for the zuul proxy so that I can respond better when the service located behind my gateway crashed / was disabled. Here is the code I took from the answer in Configuring Zuul exception

public class RabbrErrorFilter extends ZuulFilter {

private static final Logger log = LoggerFactory.getLogger(RabbrErrorFilter.class);
protected static final String SEND_ERROR_FILTER_RAN = "sendErrorFilter.ran";

@Override
public String filterType() {
    return "post";
}

@Override
public int filterOrder() {
    return Integer.MIN_VALUE; // Needs to run before SendErrorFilter which has filterOrder == 0
}

@Override
public boolean shouldFilter() {
    // only forward to errorPath if it hasn't been forwarded to already
    RequestContext ctx = RequestContext.getCurrentContext();
    return ctx.containsKey("error.status_code") && !ctx.getBoolean(SEND_ERROR_FILTER_RAN,false);
}
@Override
public Object run() {
    try {
        RequestContext ctx = RequestContext.getCurrentContext();
        Object e = ctx.get("error.exception");

        if (e != null && e instanceof ZuulException) {
            ZuulException zuulException = (ZuulException)e;
            log.error("Zuul failure detected: " + zuulException.getMessage(), zuulException);

            // Remove error code to prevent further error handling in follow up filters
            ctx.remove("error.status_code");

            // Populate context with new response values
            ctx.setResponseBody("Overriding Zuul Exception Body");
            ctx.getResponse().setContentType("application/json");
            ctx.setResponseStatusCode(500); //Can set any error code as excepted
            ctx.setSendZuulResponse(false);
        }
    }
    catch (Exception ex) {
        log.error("Exception filtering in custom error filter", ex);
        ReflectionUtils.rethrowRuntimeException(ex);
    }
    return null;
}

I checked with the debugger that the code in run () is executed when the zuul exception is thrown, but in the console log I get the following:

com.netflix.zuul.exception.ZuulException: Forwarding error

    at com.netflix.zuul.http.ZuulServlet.service(ZuulServlet.java:81) ~[zuul-core-1.1.0.jar:1.1.0]

and the response from the service behind the gateway expires with a status of 500.

- Edit * Updating spring-cloud dependencies (contains zuul 1.3.0 kernel) did not fix this

: Spring Cloud: Zuul. , Forwarding Zuul.

Zuul RibbonRoutingFilter SendErrorFilter ${error.path}, '/error. , , Spring Boots BasicErrorController. ErrorController.

Vnd, Spring ErrorController.
