Java Neo4j ProcedureException：输出字段为零的过程必须声明为无效

我在Neo4j enterprise-3.0.4中使用了一个自定义过程，在那里工作正常。但最近我切换到了最新版本，即Neo4j enterprise-3.2.1。当我尝试以自定义过程作为插件启动服务器时，它会引发以下异常：

Caused by: org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.proc.Procedures@3018c593' was successfully initialized, but failed to start. Please see the attached cause exception "Procedures with zero output fields must be declared as VOID".

请告诉我为什么在最新版本中出现此错误，正如文档中提到的，3.x之后的任何插件都将在neo4j的3.2.x版本中工作。

在我的过程中使用返回内置类型节点流时，我遇到了相同的问题。为了解决这个问题，我只创建一个新类来处理它

    public class NewNodeClass{
       public final Node newNodeObject;

       public Hashtag(Node node) { this.newNodeObject = node;}
    }

显示一些代码可能是您正在调用一些Apoc过程，这些过程也移动到了neo4j包中。我没有代码。我正在使用插件的jar文件。你在使用什么插件？自定义过程插件
