dateutils.js and interface.js throwing constant errors

See original GitHub issue

When importing and using Agenda, “d.toString” is undefined (undefined is not an object)(in Interface.js) When importing and using CalendarList “days[0].clone” is undefined (undefined is not an object)(in dateutils.js)

I freshly installed react-native-calendars (yarn add react-native-calendars). It will throw those named error right away. I tried installing earlier versions with no success.

I simply imported: import {Agenda} from “react-native-calendars”; and used “Agenda”. Same with CalendarList: import {CalendarList} from “react-native-calendars”;

TypeError: undefined is not an object (evaluating 'd.toString')
