Various php errors when clicking on ics link

I am using the date_ical module to allow users to add an event to their calendar. However, every time the ical link is clicked, I see the following series of error messages in Drupal's "Recent log messages" page:

Drupal 7.81
PHP 7.3.23
Date 7.x-2.11
Date iCal 7.x-3.10
Date iCal iCalcreator library is installed, version: 2.20.2 found
