Hello,
In case if you still need help, you need to replace the following string:

@component({

to this one:

@Component({

And this string:

template: <div #gantt_here class='gantt-chart'></div>,

to this one:

template: `<div #gantt_here class='gantt-chart'></div>`,

@nithin-neewee, DHTMLX Scheduler is a different component. I don't think it is a good idea to discuss it here.
Please, create a new topic here:
https://forum.dhtmlx.com/c/scheduler-all

And if you have the license, you can submit the support request according to the instructions in the email with the license.

It will take less time to resolve the issue if you provide the steps to reproduce it or send a ready demo.
