EdgeHandler error since v.6.4.3

Hi I use vis-network as a Hierarchical layout, using script: https://visjs.github.io/vis-network/standalone/umd/vis-network.min.js like this:

const data = {
    nodes: new vis.DataSet([]),
    edges: new vis.DataSet([])
}

const options = {

    layout: {
        hierarchical: {
            sortMethod: "directed",
            shakeTowards: "roots"
        }
    },
    locale: 'fr',
    locales: vis_fr,
    height: '600px',
    edges: {
        arrows: 'to',
        smooth: true,
        length: 250
    },
    nodes: {
        shape: shapes.task,
        widthConstraint: 100
    },
    manipulation: {
        enabled: manageTasks,
        addNode: function(node, callback) {
            location.href = base_url + 'task/add'
        }
    // ...
    }
}

It worked fine with version v6.4.0. Since version 6.4.3, I've got the following error:

TypeError: i is null

In this projet I use a click on a node to do something. And with this error, it look like that the click event is not anymore registred.
