Cannot read property 'create' of undefined -- react-dates error

Question

While adding SingleDatePicker from 'react-dates' library, I got this error. Tried everything but couldn't find the error. The code is just to display the calender and display the selected date from the user. Please help! Here is the code:

import React from 'react';
import moment from 'moment';
import { SingleDatePicker } from 'react-dates';
import 'react-dates/lib/css/_datepicker.css';

export default class ExpenseForm extends React.Component {
  state = {
    createdAt: moment(),
    calenderFocused: false
  };
  onDateChange = (createdAt) => {
    this.setState(() => ({ createdAt }));
  };

  onFocusChange = ({ focused }) => {
    this.setState(() => ({ calenderFocused: focused }));
  };

  render() {
    return (
      <div>
        <form>
          <SingleDatePicker
            date={this.state.createdAt}
            onDateChange={this.onDateChange}
            focused={this.state.calendcalenderFocused}
            onFocusChange={this.onFocusChange}
          />
        </form>
      </div>
    );
  }
};

The error I am getting in the chrome-dev-tool:

Uncaught TypeError: Cannot read property 'create' of undefined

The above error occurred in the <withStyles(SingleDatePicker)> component:
    in withStyles(SingleDatePicker) (created by ExpenseForm)
    in form (created by ExpenseForm)
    in div (created by ExpenseForm)
    in ExpenseForm (created by AddExpensePage)

Answer 1

I got the same error in my tests and adding import 'react-dates/initialize'; fixed it.

Refer to https://github.com/airbnb/react-dates#initialize

Answer 2

import 'react-dates/initialize';

As of v13.0.0 of react-dates, this project relies on react-with-styles. If you want to continue using CSS stylesheets and classes, there is a little bit of extra set-up required to get things going. As such, you need to import react-dates/initialize to set up class names on our components.
