Your Question (问题描述)

After successfully deploying HugeGraph server and HugeGraph-Hubble, I encountered errors while running GremlinApiTests and attempting to create a graph. The system reported a java.lang.AssertionError with a status of 400. The error message indicates that 'gremlin-groovy is not an available GremlinScriptEngine', which seems to stem from a configuration issue or missing dependency.

Error Details: java.lang.AssertionError: Response with status 400 and content: {"exception":"java.lang.IllegalArgumentException", "message":"gremlin-groovy is not an available GremlinScriptEngine", "cause":"[java.lang.IllegalArgumentException]"} Expected: 200 Actual: 400

To resolve the java.lang.AssertionError indicating that 'gremlin-groovy is not an available GremlinScriptEngine' when running GremlinApiTests on HugeGraph, follow these steps:

Ensure Dependencies: Add the gremlin-groovy dependency to your pom.xml:

<dependency>
    <groupId>org.apache.tinkerpop</groupId>
    <artifactId>gremlin-groovy</artifactId>
    <version>3.4.10</version> <!-- Use the appropriate version -->
</dependency>

Check Configuration: Verify that the gremlin-groovy script engine is correctly configured in your HugeGraph server configuration. Ensure that the gremlin-groovy script engine is listed in the scriptEngines configuration in gremlin-server.yaml:

scriptEngines: {
  gremlin-groovy: {
    plugins: {
      org.apache.hugegraph.plugin.HugeGraphGremlinPlugin: {},
      org.apache.tinkerpop.gremlin.server.jsr223.GremlinServerGremlinPlugin: {},
      org.apache.tinkerpop.gremlin.jsr223.ImportGremlinPlugin: {

        ],
        methodImports: [java.lang.Math#*]
      },
      org.apache.tinkerpop.gremlin.jsr223.ScriptFileGremlinPlugin: {
        files: [scripts/empty-sample.groovy]
      }
    }
  }
}

Initialize Script Engine: Ensure that the script engine is initialized properly in your test setup. You might need to explicitly initialize the gremlin-groovy script engine before running the tests:

import org.apache.tinkerpop.gremlin.groovy.jsr223.GremlinGroovyScriptEngine;
import javax.script.ScriptEngineManager;

public class GremlinApiTest extends BaseApiTest {

    static {
        // Initialize the GremlinGroovyScriptEngine
        ScriptEngineManager manager = new ScriptEngineManager();
        manager.registerEngineName("gremlin-groovy", new GremlinGroovyScriptEngine());
    }

    // Your test methods
}

Set Language in GremlinRequest: Ensure that your GremlinRequest class in GremlinAPI is correctly setting the language to gremlin-groovy:

public static class GremlinRequest implements Checkable {

    @JsonProperty
    private String gremlin;
    @JsonProperty
    private Map<String, Object> bindings = new HashMap<>();
    @JsonProperty
    private String language = "gremlin-groovy";
    @JsonProperty
    private Map<String, String> aliases = new HashMap<>();

    // Other methods...
}

By ensuring that the gremlin-groovy dependency is included, the script engine is properly initialized and configured, and the GremlinRequest class is correctly set up, you should be able to resolve the java.lang.AssertionError and run your GremlinApiTests successfully ^[1].
