When the "Input type" was set to "Date" in "Template Variables" of "Elements", WARNING was displayed on the screen for creating a new resource or editing a resource.
Error : Trying to access array offset on value of type null
It seems that $_style["icon_calendar_close"] on line 760 of the core/functions/actions/mutate_content.php file is the cause.
Changing $_style["icon_calendar_close"] to ManagerTheme::getStyle('icon_calendar_close') will make the WARNING disappear.
However, when I clicked on the displayed icon, the Datepicker did not appear.
Confirmed this issue with Evolution CMS version 3.1.10.
