Exception when running sample code

New to the Prometheus RsocketProxy Client. When I attempt to run the example code provided on the site, I get an exception as shown below - please advise? (Can provide other details as needed.)

```
import io.micrometer.prometheus.rsocket.PrometheusRSocketClient;
import io.rsocket.transport.netty.client.TcpClientTransport;
import org.apache.commons.lang3.exception.ExceptionUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.client.RestTemplate;
public class MLModelRSocketClient {
private static final Logger LOG = LoggerFactory.getLogger(MLModelRSocketClient.class);

public static void main(String[] args) {

try {
PrometheusMeterRegistry meterRegistry = new PrometheusMeterRegistry(PrometheusConfig.DEFAULT);

LOG.info("Building RSocket client...");

PrometheusRSocketClient client = PrometheusRSocketClient
.build(meterRegistry,
TcpClientTransport.create("localhost", 7001))
.connect();
} catch (Exception ex) {
LOG.error("Error occurred...");
LOG.error(ExceptionUtils.getStackTrace(ex));
}

}
}
```

```

Start by running the PrometheusRSocketClient example from the issue against the documented sample setup and capture the complete exception, since the excerpt omits its cause. Compare the result with the site's example and record a reproducible failing case; done means the example runs or the issue has a confirmed, documented cause.
