Nacos Instance InstanceId issue

[onoeono]

Describe the bug
Get an instance via NamingService, and the instanceId is null

I also try to add preserved.instance.id.generate=snowflake in nacos properties meta
but instanceId is still null
Expected behavior
when registry to nacos, nacos should generate an unique id for this instance

Actually behavior
instanceId is null

• Version Spring Cloud version 2023.0.0 Spring Cloud Alibaba version 2023.0.0.0-RC1 Nacos Client version 2.3.0

i upgrade nacos server to 2.2.3 and try to get instanceId, it's still null
here is my simple code

@SpringBootApplication
public class CloudApplication {
	@Autowired
	private NacosDiscoveryProperties nacosDiscoveryProperties;

	public static void main(String[] args) {
		SpringApplication.run(CloudApplication.class, args);
	}

	@Bean
	public NamingService namingService() throws NacosException {
		return NamingFactory.createNamingService(nacosDiscoveryProperties.getServerAddr());
	}
}

@RestController
@RequestMapping("/test")
public class TestController {
        @Autowired
	private NamingService namingService;
	@Value("${spring.application.name}")
	private String applicationName;

        @GetMapping("/unique")
	public Object unique() throws NacosException {
		List<Instance> allInstances = this.namingService.getAllInstances(this.applicationName);
		Instance instance = allInstances.get(0);

		String instanceId = instance.getInstanceId();
		System.out.println("instanceId = " + instanceId);
		return allInstances;
	}
}

here is the response

[
    {
        "ip": "my ip address",
        "port": 7088,
        "weight": 1.0,
        "healthy": true,
        "enabled": true,
        "ephemeral": true,
        "clusterName": "DEFAULT",
        "serviceName": "DEFAULT_GROUP@@cloud-service",
        "metadata": {
            "preserved.register.source": "SPRING_CLOUD"
        },
        "ipDeleteTimeout": 30000,
        "instanceHeartBeatInterval": 5000,
        "instanceHeartBeatTimeOut": 15000
    }
]
