error about react-gantt HOT 2 OPEN

Can you send me what you are doing that causes this issue?

from react-gantt.

I want to create a process scheduling algorithm simulator thats why i want to create ganttchart using react.js library.
And for that I'm using this given codes:
import ReactGantt, { GanttRow } from 'react-gantt';

class Demo extends Component {
render() {
return (
<ReactGantt
templates={{
myTasks: {
title: 'My Tasks',
steps: [
{
name: 'Task Phase One',
color: '#0099FF'
},
{
name: 'Task Phase Two',
color: '#FF9900'
}
]
}
}}
leftBound={moment().set({hour: 0, date: 30, month: 5, year: 2016}).toDate()}
rightBound={moment().set({hour: 0, date: 29, month: 8, year: 2016}).toDate()}
>
<GanttRow
title="Task 1"
templateName="myTasks"
steps={[
moment().set({hour: 0, date: 1, month: 6, year: 2016}).toDate(),
moment().set({hour: 0, date: 4, month: 8, year: 2016}).toDate(),
moment().set({hour: 0, date: 17, month: 8, year: 2016}).toDate()
]}
/>
<GanttRow
title="Task 1"
templateName="myTasks"
steps={[
moment().set({hour: 0, date: 27, month: 2, year: 2016}).toDate(),
moment().set({hour: 0, date: 9, month: 7, year: 2016}).toDate(),
moment().set({hour: 0, date: 22, month: 7, year: 2016}).toDate()
]}
/>

);
}
}

Can you suggest me some ways to creating simulator for scheduling algoritm's Gantt charts?
