[GitHub] [incubator-hugegraph] joyemang33 opened a new issue, #2138: [Bug] Unexpected exception [java.lang.IllegalArgumentException] when ordering edges by an aggregate such as "value().min()"

joyemang33 opened a new issue, #2138:
URL: https://github.com/apache/incubator-hugegraph/issues/2138

   ### Bug Type (问题类型)
   
   gremlin (结果不合预期)
   
   ### 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)
   
   - Server Version: 1.0.0 (Apache Release Version)
   - Backend: RocksDB x nodes, HDD or SSD 
   - OS: xx CPUs, xx G RAM, Ubuntu 2x.x / CentOS 7.x 
   - Data Size:  10 vertices, 50 edges 
   
   ### Expected & Actual behavior (期望与实际表现)
   
   Here are the two Gremlin queries we will execute. They should yield the same results because for each vertex, the expression 'values("prop10") = values("prop10").min()' must hold. However, the second query returns an unexpected expectation java.lang.IllegalArgumentException. 
   
   Would it be possible for you to investigate this matter and provide a solution to this issue? We greatly appreciate your attention to this matter and thank you for your prompt response.
   
   ```
   Gremlin1: hugegraph.traversal().E().order().by(values("prop10"))
   Result1:

   Sure, the information from server is ```ERROR:root:{'exception': 'java.lang.IllegalArgumentException', 'message': 'The provided traverser does not map to a value: e[L695415354955923456>6>>L695415355421491200][695415354955923456-Elabel6->695415355421491200]->[PropertiesStep([prop10],value), FoldStep, MinLocalStep]', 'cause': '[java.lang.IllegalArgumentException]'}```.

   Sorry, it expects a fold() step and should be: `g.E().order().by(values("prop10").fold().min(local))`.
   
   A further question, in this scene why not use this way `g.E().order().by("prop10")`?

   @javeme Hi, I use ```hugegraph.traversal().E().order().by(values("prop10").min(local)) ``` but meet another unexpected exception that I never met ```java.lang.ClassCastException', 'message': 'java.lang.Integer cannot be cast to java.lang.Iterable```. Would you be able to assist me in verifying this? Thank you kindly.

   do you want a `min(local)` step:
   `hugegraph.traversal().E().order().by(values("prop10").min(local))`

   Thank you very much for your response. I am interested in implementing something similar to min(local), and I plan to test whether this will still result in the same exception when using "local" as soon as possible. However, based on the information in the Gremlin documents found at http://tinkerpop-gremlin.cn/#by-step, it appears that omitting "local" may also be acceptable. Would you be able to assist me in verifying whether there is an issue or bug with this? Thank you kindly.

   > seems some edges do not have property 'prop10', please try `order().by(choose(values("xx"), values("xx").min(), constant(0)))`
   
   I appreciate your help and your previous query works well. However, I have observed that order().by(values("prop10")) can be executed successfully even when some edges do not have the "prop10" property. This is an advantage of HugeGraph, as other Graph Databases such as OrientDB cannot handle this situation.
   
   Due to this difference, there appears to be an inconsistency in being unable to order the above case directly. I was wondering if there is a way to resolve this inconsistency and enable us to order the edges directly without the need for ```choose``` statements. Would it be possible for you to fix this issue?

   Hi, Many thanks again for your valuable feedback, and the `g.E().order().by("prop10")` is OK to execute which helps me a lot.
    
   However, I try the ```hugegraph.traversal().E().order().by(values("prop10").fold().min(local))``` where still returns an unexpected exception ```java.lang.IllegalArgumentException```.
   
   In my opinion, there may be some bugs during the execution of the latter query, which could be similar to the issue encountered previously (#2124). My intention is to order the edges based on the minimum property value of "prop10" among their out-vertices. However, when I tried to execute the query ```hugegraph.traversal().E().order().by(__.outV().values("prop10").fold().min(local))```, it resulted in an unexpected exception.
   
   I noticed that ```hugegraph.traversal().E().order().by(values("prop10").min(local))``` is a reduction of the above query, and the above query might be applicable in some contexts for some users. Would it be possible for you to verify whether there is a bug in the execution process? Your assistance in resolving this issue would be greatly appreciated.
