Cannot access overflowdb.Graph, driver.getWholeGraph();

[MaikkiaM]

I just started working with Plume. I'm about to do my master's thesis and will do it with Plume. I am currently still working on a first prototype.

My problem is that I can't pull the whole graph through "driver.getWholeGraph ();" with the error message "Cannot access overflowdb.Graph" but I can export it into a XML-File. I've already tried back and forth but I can't really come to a solution.

I am currently configuring the backend storage up and down, but so far without any results.
Any ideas?

From the example project from git, the export to a graph also works smoothly.

        Workaround with a reimport works: 

        System.out.println("Projecting graph");
        extractor.project();
        driver.exportGraph("./graph.xml");

        TinkerGraph graph = TinkerGraph.open();
        graph.io(graphml()).readGraph("./graph.xml");
        

        System.out.println("Done!");
