PathFindingLink Render issue - Uncaught TypeError: Cannot read properties of undefined (reading '75')

[horizon-sk]

I am trying to use dagre example to render custom nodes with PathFindingLinkModel but it always crashes when the number of nodes are more that cannot fit in the canvas view.

This exception doesn't occur if I switch to DefaultLinkModel.

Also, I am NOT using SmartRouting, but with SmartRouting turned on, same issue is there.

Please advice how to circumvent this issue.

I am using below code -

const autoDistribute = () => {
    let dagreEngine = new DagreEngine({
        graph: {
            rankdir: 'TB',
            ranksep: 200,
            edgesep: 400,
            nodesep: 300,
            ranker: 'network-simplex',
            marginx: 20,
            marginy: 20
            //rankdir: 'RL',
            //ranker: 'longest-path',
            //marginx: 25,
            //marginy: 25
        },
        includeLinks: false
    });
    dagreEngine.redistribute(props.engine.getModel());

    reroute();
    
    props.engine.repaintCanvas();
};

const reroute = () => { props.engine .getLinkFactories() .getFactory(PathFindingLinkFactory.NAME) .calculateRoutingMatrix(); };
