### Bug Type (问题类型) other exception / error (其他异常报错) ### Before submit - [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - HugeGraph Version: 0.12.0 - Storage Backend: inmemory - Mixed Index Backend: none - Link to discussed bug: none - Operating system: macOS 13.2.1 - API/Driver: Java ### Expected & Actual behavior (期望与实际表现) I first randomly create a graph. Then when I run the following query: `g.E().inV().bothE('el0').fold().as('x').E().where(__.count()).where(within('x'))` is thrown with an exception. I think this query is syntactically correct, but I keep triggering this kind of problem. **Expected behavior:** No exception should be expected to throw. Or futher messages or prompts should be thrown. **Actual behavior:** A `groovy.lang.MissingMethodException` is thrown. And I'm not really sure whether this problem should happen so I report this. I succeed this kind of collection transition when replacing `g.E()` with `g.V()`. So I guess there's some problems of `g.E()` syntax, and maybe it doesn't support midterm `E()` syntax. ``` HugeGraph exception : groovy.lang.MissingMethodException: No signature of method: org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.DefaultGraphTraversal.E() is applicable for argument types: () values: [] Possible solutions: by(groovy.lang.Closure), is(java.lang.Object), use([Ljava.lang.Object;), use(java.util.List, groovy.lang.Closure), use(java.lang.Class, groovy.lang.Closure), any() ``` ### Vertex/Edge example (问题点 / 边数据举例) ```javascript Steps to reproduce: We create a graph with 10 nodes and 20 edges. We try to make it clear to reproduce the bugs, {}hope{} to not cause much inconvenience to your reviewing, but we believe the problem does exist. Following the following graph data generation query, we can reproduce the bugs: ``` ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) _No response_ -- This is an automated message from the Apache Git Service.
