Lumise plugin causing error when placing order (Woocommerce)

Getting error message (see attached image) when place order button is clicked.
When the Lumise plugin is deactivated, the issue is resolved.

Here is the log that was created:

Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in /home/customer/www/cre8teez.com/public_html/wp-content/plugins/lumise/core/includes/database.php:1706
