NotYetImplemented error in HTMLCanvasElement

Getting an error with message “NotYetImplemented” from utils.js I get the error while using nodejs server, what this exact error means? When I’m using “ng serve” there is not such error.

I’m using line chart from ng2-charts module. Full Stack Trace:

I’ve just gotten this with the lottie library. It’s happening right as soon as the module is initialized:

var ImagePreloader = (function(){

    var proxyImage = (function(){
        var canvas = createTag('canvas');
        canvas.width = 1;
        canvas.height = 1;
        var ctx = canvas.getContext('2d');
        ctx.fillStyle = 'rgba(0,0,0,0)';
        ctx.fillRect(0, 0, 1, 1);
        return canvas;
    }())

If it were in my application I would just wrap this in a conditional and only execute if inside the browser. But it seems to be too deep to reach. Anyone have any suggestions?

For me, the above solution (@rtyx) doesn’t work, but if I replace this

<div style="display: block" *ngIf="isBrowser">
    <canvas baseChart
                    [datasets]="datasets"
                    [options]="barChartOptions"
                    [legend]="barChartLegend"
                    [chartType]="'bar'"
                    [colors]="statisticsService.colors"
                    (chartHover)="chartHovered($event)"
                    (chartClick)="chartClicked($event)">
    </canvas>
</div> 

by this, It’s works for me!

ngAfterViewInit(): void { if (this.isBrowser) { this.ctx = this.canvas.nativeElement.getContext( '2d', ) as CanvasRenderingContext2D; .... } }
