<!-- Answer -->
你遇到的错误 “The traversal source [hugegraph] for alias [g] is not configured on
the server” 通常是因为 `gremlin-server.yaml` 配置文件中没有正确配置 `graphs` 部分，导致 Gremlin
Server 启动后没有加载 HugeGraph 的图实例。
根据 HugeGraph 官方配置文档，建议检查以下几点：
1. **gremlin-server.yaml 配置**
确保 `graphs` 部分已正确填写，例如：
```yaml
graphs: {
g: conf/hugegraph.properties
}
```
其中 `g` 是 Gremlin 的 traversal source 别名（通常为
`g`），`conf/hugegraph.properties` 是你的 HugeGraph 配置文件路径。
2. **channelizer 配置**
如果你需要通过 Gremlin Console 连接，建议将 `channelizer` 设置为 WebSocket：
```yaml
channelizer:
org.apache.tinkerpop.gremlin.server.channel.WebSocketChannelizer
```
或者使用支持 HTTP 和 WebSocket 的：
```yaml
channelizer:
org.apache.tinkerpop.gremlin.server.channel.WsAndHttpChannelizer
```
3. **初始化图数据**
修改配置后，务必执行初始化脚本（如 `init-store.sh`），并重启 HugeGraph Server 和 Gremlin Server。
4. **配置文件路径**
路径要确保是绝对路径或相对于 Gremlin Server 启动目录的相对路径。
5. **示例配置片段**
参考官方文档的配置示例：[config-guide.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/en/docs/config/config-guide.md)
```yaml
graphs: {
g: conf/hugegraph.properties
}
scriptEngines: {
gremlin-groovy: {
plugins: {
org.apache.hugegraph.plugin.HugeGraphGremlinPlugin: {},
org.apache.tinkerpop.gremlin.server.jsr223.GremlinServerGremlinPlugin: {},
org.apache.tinkerpop.gremlin.jsr223.ImportGremlinPlugin: {
classImports: [ ... ]
}
}
}
}
```
如果你已经按照上述方式配置但仍然报错，请检查：
- `hugegraph.properties` 文件路径是否正确
- 是否有权限访问该文件
- 是否有其他端口或服务冲突
目前没有发现 HugeGraph 1.5.0 与 Gremlin Server 3.7.3 存在已知兼容性问题，主要还是配置问题导致 traversal
source 没有被加载
[参考1](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/en/docs/config/config-guide.md)
[参考2](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/src/assembly/travis/conf-raft3/gremlin-server.yaml)。
如还有问题，可以贴出你的 `gremlin-server.yaml` 关键配置片段，便于进一步排查。
