RangeError: invalid date

[Aniruddh1707]

I am using react-light-calendar in my react app and it was working fine earlier but now it's not working and it gives "RangeError: invalid date" error when i try to open calendar.
I have also update the version of react and react-dom to "react": "^16.3.0", "react-dom": "^16.3.0" according to instruction.
I am using "@lls/react-light-calendar": "^2.2.0" this version in my react app.
But it gives "RangeError: invalid date" everytime.

constructor(props) {
super(props);
const date = new Date();
const startDate = date.getTime();
const endDate = date.getTime();
this.state = {
startDate,
endDate
}
}

<ReactLightCalendar startDate={this.state.startDate} endDate={this.state.endDate} onChange={this.onChange} range displayTime = {false}
disableDates={date => date >= new Date().getTime()}/>

Can you please provide the solution?
