Gremlin driver throwing GraphMalformedException after updating gremlin driver to 3.4.0

[boltmillee]

This is in reference to microsoft/spring-data-gremlin#196 . I followed the steps and updated the gremlin driver but I am getting a different issue because of that. Exception message attached

Caused by: org.apache.tinkerpop.gremlin.driver.exception.ResponseException:

GraphSON v3 is not supported in Azure Gremlin Api, we had that issue as well and we changed gremlin client serializer to GRAPHSON_V2D0
for example:

private Cluster createGremlinCluster() throws GremlinIllegalConfigurationException {
    final Cluster cluster;

    try {
        cluster = Cluster.build(this.gremlinConfig.getEndpoint())
                .serializer(Serializers.GRAPHSON_V2D0.toString())
                .create();
    } catch (IllegalArgumentException e) {
        throw new GremlinIllegalConfigurationException("Invalid configuration of Gremlin", e);
    }

    return cluster;
}

hope this helps.

@backwind1233 could you please help route this issue from @boltmillee?

@omerkisoss Thanks for the help. This seems to be working fine with custom queries. However, I have a few GremlinRepositories where the default findById() and findAll() methods are giving this issue. Is there any solution for that also?

hope this helps.

@omerkisoss I tried with above code with gremlin driver version 3.4.0 but I am getting the same timeout exception I was getting with version 3.2.4: java.lang.RuntimeException: java.util.concurrent.TimeoutException: Timed out while waiting for an available host - check the client configuration and connectivity to the server if this message persists

@msingal003
That is probably because you didnt configure all gremlin repositories properly, here is a sample of Gremlin Repositories configuration:

@Configuration
@EnableGremlinRepositories(basePackages = "com.example")
@EnableConfigurationProperties(GremlinProperties.class)
@PropertySource("classpath:application.yml")
@Slf4j
public class GremlinRepoConfig extends AbstractGremlinConfiguration {

    private final GremlinProperties gremlinProps;

    @Autowired
    public GremlinRepoConfig(GremlinProperties gremlinProps) {
        this.gremlinProps = gremlinProps;
    }

    @Override
    public GremlinConfig getGremlinConfig() {
        log.info("Gremlin Configurations loaded: {}", gremlinProps.toString());
        return GremlinConfig.builder(gremlinProps.getEndpoint(), gremlinProps.getUsername(), gremlinProps.getPassword())
                .serializer(gremlinProps.getSerializer())
                .maxConnectionPoolSize(gremlinProps.getMaxConnectionPoolSize())
                .maxInProcessPerConnection(gremlinProps.getMaxInProcessPerConnection())
                .maxSimultaneousUsagePerConnection(gremlinProps.getMaxSimultaneousUsagePerConnection())
                //.maxWaitForConnection(gremlinProps.getMaxWaitForConnection())
                //.keepAliveInterval(gremlinProps.getKeepAliveInterval())
                .build();

    }

hope this helps, let me know if you still having issues.

Thank you for your comments on the issue, we have deprecated Spring Data Gremlin support for Cosmos DB,
if it is important to you, please vote on this issue #24773.

[manishmsfte]

Please use .NET Gremlin SDK v 3.4.13, refer the compatible version list here https://learn.microsoft.com/en-us/azure/cosmos-db/gremlin/support#compatible-client-libraries
