Bluesky Gephi Plugin: IllegalArgumentException: Node id=-1 is invalid

[simosathan9]

The same issue was previously reported and resolved in Issue #238 .

Expected Behavior

Open project file and initialize graph.

Current Behavior

When importing a network with less than approximately 20.000 nodes the graph is initialized. When I attempt to open a larger project file that contains more than 30.000 nodes I get the following exception
