Can't scale or rotate fabricJs Image, Rect, Ellipse

As in the title, I'm using fabricJS 4.6.0 with VueJs 3.

I'm trying to simply setup fabric with resizable rectangles.

My problem is accessing the object canvas outside the initFabric method.

I can't resize or rotate the rectangle, just move it.

The only way to make it works is declare canvas as const if I use this.canvas doesn't work.

here the jsfiddle https://jsfiddle.net/8vzc3bj5/19/

initFabric: function () {
    var canvasEl = this.$refs.canvas;
    canvasEl.width = 1920;
    canvasEl.height = 1080;

    const canvas = new fabric.Canvas(canvasEl, {
        // isDrawingMode: true,
        centeredScaling: true,
        backgroundColor: "#fff",
        selectionBorderColor: "rgba(255, 255, 255, 0.8)",
        selectionColor: "rgba(255, 255, 255, 0.8)",
        selectionLineWidth: 2,
        borderColor: "gray",
        cornerColor: "black",
        cornerSize: 12,
        transparentCorners: true,
    });

    canvas.on("selection:created", this.handleSelection);
    canvas.on("selection:updated", this.handleSelection);

    canvas.on("after:render", this.updateCanvas);
    canvas.on("object:modified", this.updateCanvas);
    canvas.on("object:added", this.updateCanvas);
    canvas.on("object:removed", this.updateCanvas);

    canvas.on("mouse:wheel", (opt) => {
        var delta = opt.e.deltaY;
        var zoom = canvas.getZoom();
        zoom *= 0.999 ** delta;
        if (zoom > 20) zoom = 20;
        if (zoom < 0.01) zoom = 0.01;
        canvas.zoomToPoint(
            { x: opt.e.offsetX, y: opt.e.offsetY },
            zoom
        );
        opt.e.preventDefault();
        opt.e.stopPropagation();
    });

    this.$nextTick(() => {
        var rect = new fabric.Rect({
            left: 100,
            top: 50,
            fill: "yellow",
            width: 200,
            height: 100,
            stroke: "lightgreen",
            strokeWidth: 4,
            zoomX: 1,
            zoomY: 1,
            dirty: true,
        });
        canvas.add(rect);
        rect.center();
        canvas.setActiveObject(rect);
        canvas.bringToFront(rect);
        canvas.renderAll();
    });
    this.resizeCanvas();
},

Thanks
