Undefined index: errors showing on widget

As of today June 27, seeing this error in widget area on homepage where we display our google reviews. The reviews themselves still appear properly, below these lines of error codes. The codes also appear in the wp-admin back end of the site. I’ve attached screenshots here but have hidden that section on the live site for now until this is resolved, because it’s a HUGE problem for us.
