Nodes info response has wrong assumptions about existing parameters

[spinscale]

This occured when trying to retrieve nodes info via the new java client (version 8.2.0)

NodesInfoResponse nodesInfoResponse = client.nodes().info();

Repro test case using testcontainers

    private static GenericContainer container;
    private static RestClient restClient;
    private static ElasticsearchClient client;

    @BeforeAll
    public static void startContainer() {
        container = new ElasticsearchContainer("docker.elastic.co/elasticsearch/elasticsearch:8.2.0"){
            @Override
            protected void containerIsStarted(InspectContainerResponse containerInfo) {
            }
        };
        container.addEnv("discovery.type", "single-node");
//        container.addEnv("path.repo", "/tmp/");
        container.withEnv("xpack.security.enabled", "false");
        container.withEnv("ES_JAVA_OPTS", "-Xms4g -Xmx4g");
        container.addExposedPorts(9200);
        container.setWaitStrategy(new LogMessageWaitStrategy().withRegEx(".*(\"message\":\\s?\"started\".*|] started\n$)"));

        container.start();
        container.followOutput(new Slf4jLogConsumer(LoggerFactory.getLogger(LangDetectProcessorIntegrationTests.class)));

        // Create the low-level client
        restClient = RestClient.builder(new HttpHost("localhost", container.getMappedPort(9200))).build();
        ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
        client = new ElasticsearchClient(transport);
    }

    @AfterAll
    public static void stopContainer() throws IOException {
        if (restClient != null) {
            restClient.close();
        }
        if (container != null) {
            container.close();
        }
    }

    @Test
    public void testLangDetectPlugin() throws Exception {
        // here comes the exception
        NodesInfoResponse nodesInfoResponse = client.nodes().info();
    }

Exception

co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch.nodes.info.NodeInfoSettings: co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'NodeInfoPath.repo' (JSON path: nodes['MWtGcjMvSk-VO_a76Vaglw'].settings.path) (line no=1, column no=923, offset=-1)

If you set path.repo (i.e. uncomment in the above code snippet). Then another exception occurs

co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch.nodes.info.NodeInfoSettings: co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'NodeInfoDiscover.seedHosts' (JSON path: nodes.L289RMUaRFmdPARutNe2oA.settings.discovery) (line no=1, column no=974, offset=-1)

This setting is not set as discovery type is set to single node...
