[Bug] Throw MissingMethodException for E() syntax
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 与 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)
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:

I think is the middle E() here.
g.E().inV().bothE('el0').fold().as('x').E().where(__.count()).where(within('x'))
