Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

Hi there,

I’ve downloaded a trial of the Event Calendar and I’m just trying out all the features and customisations to ensure it will do exactly what I need before making a purchase.

Simply using it out of the box, the only properties I’ve added are 4 “calendars”. I’m getting the below error appear in the console randomly. If I highlight the text in “Event name” and the mouse ends up dragged over the calendar itself prompting the popup “You have unsaved changes…” This is sometimes the point when I get the console message. Sometimes it’s when I try to add a second event.

When this happens I can’t click anything and no key presses are registered.

An easy way to recreate the error is to Double Click the calendar to create an event or click " + Create Event", then whilst the right hand pane for adding an event is visible, click the + Create Event" button again. You will receive the “You have unsaved changes…” popup and see the error in the console and be unable to click anything.
