So I’m trying to transition my project from d5 to d6, and came across the error of event being deprecated. I’ve tried converting it based off The Migration Guide but it only throws errors.
Here is my code after trying to convert it
_zoomConfig = () => {
const selector = d3Select(`#${this.state.id}-${CONST.GRAPH_WRAPPER_ID}`);
const zoomObject = d3Zoom().scaleExtent([this.state.config.minZoom, this.state.config.maxZoom]);
if (!this.state.config.freezeAllDragEvents) {
zoomObject.call(d3Zoom()
.on("zoom", function zoomed({transform}, d) {
d3SelectAll(`#${this.state.id}-${CONST.GRAPH_CONTAINER_ID}`)
.attr("transform", transform);
}));
}
if (this.state.config.initialZoom !== null) {
zoomObject.scaleTo(selector, this.state.config.initialZoom);
}
// avoid double click on graph to trigger zoom
selector.call(zoomObject).on("dblclick.zoom", null);
};
However, I keep getting this error thrown when it’s like this?

It seems to be coming from the zoomObject.call() line, however, I’ve confirmed (printed) zoomObject and it prints as this
ƒ zoom(selection) {
selection.property("__zoom", defaultTransform).on("wheel.zoom", wheeled, {
passive: false
}).on("mousedown.zoom", mousedowned).on("dblclick.zoom", dblclicked).filter(t…
