Link path is not showing

Hello guys!

I’m faced of this issue, When I render the simple diagram the path of link is not showing, I attach a gif,

https://drive.google.com/open?id=1NExH1wrOE_R6AXx_2dDFkhT4KLTI64V4

on my code ` const { engine } = this.state;

    engine.installDefaultFactories();

    //2) setup the diagram model
    var model = new DiagramModel();

    //3-A) create a default node
    const node1 = new DefaultNodeModel("Node 1", "rgb(255,99,66)");
    let port1 = node1.addOutPort("Out");
    node1.setPosition(100, 100);

    //3-B) create another default node
    const node2 = new DefaultNodeModel("Node 2", "rgb(192,255,0)");
    let port2 = node2.addInPort("In");
    node2.setPosition(400, 100);

    // link the ports
    let link1 = port1.link(port2);
   // (link1 as DefaultLinkModel).addLabel("Hello World!");

    //4) add the models to the root graph
    model.addAll(node1, node2, link1);

    //5) load model into engine
    engine.setDiagramModel(model);

    this.setState({
        diagramEngine: engine,
    });`

Any luck with this ?. I’m experiencing the same issue.

That was the first thing I checked. if you see the follow image with gray backgrond color , seems that path lost the relation between the nodes
