   ### Before submit
   
   - [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与

confirmed and searched that there are no similar problems in the historical 
issue and documents)

   问题1：这个需求优化的接口是不是 org.apache.hugegraph.api.graph.EdgeAPI#list 接口
   
   问题2：如果是该接口的话，那么我理解是如果查询的 label 不为空，那么直接从 schema 中判断是否存在对应的 
edgelabel，但是需求描述是“如果顶点类型不具有该类型边”，我的判断好像是直接判断 label，并没有判断到顶点
   
   问题3：如果我上面的理解没有错误的话，那么添加的代码大概如下图1，我返回一个空迭代器，但是当 page != null 
成立时，会报错，大致调用大概如下图2，我问了ChatGPT和查阅了部分文档，不知道这里怎么返回空，如果有相关文档的话，请发送一下，我去看看
