React Date-Picker is unable to process a date input

Recently, I've been working on integrating a date picker into my application. I came across this helpful library that provides a date picker component: https://www.npmjs.com/package/react-date-picker

So far, I have set up the component in the following manner:

        <Grid item xs={7}>
            <DatePicker
                name="Date"
                value={this.getDate}
                onChange={this.handleDateChange}
            />
        </Grid>

The function 'getDate' is responsible for retrieving the current date and converting it to the appropriate format. Here's how it looks:

  getDate = () => {
    const dateToday = Service.todaysDate //service returns a string so we convert
      return new Date(dateToday)
}

Despite my efforts, I keep encountering a perplexing TypeScript error:

Type '() => Date' is not assignable to type 'Date | Date[] | undefined'.   Type '() => Date' is missing the following properties from type 'Date[]': pop,

As a newcomer to react development, I am struggling to make sense of this issue. Any guidance or assistance would be greatly appreciated. Thank you.

It is recommended to bind values with actual JavaScript variables rather than functions. Additionally, events should be bound to lambda expressions. In your render() function, consider adding the following:

let currentDate = this.getCurrentDate();
return  (<Grid item xs={7}>
        <DatePicker
            name="Date"
            value={currentDate}
            onChange={(event) => this.handleDateChange(event)}
        />
    </Grid>);
