“Deprecated” message in log

I can see the following line being printed throughout my error log at random moments (presumably when visitors are on the checkout page):

PHP Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated in /home/[user]/public_html/wp-content/plugins/revolut-gateway-for-woocommerce/includes/traits/wc-revolut-helper-trait.php on line 485
