Error Cannot read property 'getBoundingClientRect' of null in d3-gantt charts

Hi all when am trying to create the timeline chart I get the below error.I imported both d3 and d3-timeline

import * as d3timelines from 'd3-timelines';
import * as d3 from 'd3';
export class DashboardThreadedComponent implements OnInit {
 private data: any = [
        {label: 'person a', times: [
            {starting_time: 1355752800000, ending_time: 1355759900000},
            {starting_time: 1355767900000, ending_time: 1355774400000}]},
        {label: 'person b', times: [
            {starting_time: 1355759910000, ending_time: 1355761900000}]},
        {label: 'person c', times: [
            {starting_time: 1355761910000, ending_time: 1355763910000}]},
        ];

private chart: any;
 constructor(
        private cookieService: CookieService,
        private modalService: NgbModal,
        private bpeService: BPEService,
        private userService: UserService,
        private router: Router,
        private route: ActivatedRoute,
        public appComponent: AppComponent
  ) {}

    ngOnInit() {

        this.chart = d3timelines.timelines();

        d3.select('.timeline').append('svg').attr('width', 500)
        .datum(this.data).call(this.chart);

    }
}
}

But am getting the below error

ERROR TypeError: Cannot read property 'getBoundingClientRect' of null

Any one here that can help to fix it .Thanks alot

the timeline element probably not fully created in ngOnInit yet

To check if this is the case try:

setTimeout(() => {

        this.chart = d3timelines.timelines();

        d3.select('.timeline').append('svg').attr('width', 500)
        .datum(this.data).call(this.chart);

},1000)
