Hello, I updated my PHP settings at webhost (siteground) and see the following error in PHP 8.3.1  
_this warning displays:_  
Warning: Trying to access array offset on value of type null in /home/customer/www/REMOVED-for-SECURITY/public\_html/wp-content/plugins/gravityformschainedselects/includes/class-gf-field-chainedselect.php on line 526

in PHP 8.0.30  
_same warning displays:_  
Warning: Trying to access array offset on value of type null in /home/customer/www/REMOVED-for-SECURITY/public\_html/wp-content/plugins/gravityformschainedselects/includes/class-gf-field-chainedselect.php on line 526

in PHP 7.4.33  
NO WARNING (YAY)  
Error disappears.

SO, how do we fix this so that I can update PHP and not have this error display?

Thanks in advance.
