Warning: expected parameter

Hi,

and thx for reading this problem, I hope someone can help me…
when designing our website we need extra options for our clothing (all clothing have to have the same options)
we’ve put in the options in the plugin and get following error on the shopping site as we open it in a browser:

Warning: array_map(): Expected parameter 2 to be an array, null given in /home/busteae154/domains/mrtee.nl/public_html/wp-content/plugins/extra-product-options-for-woocommerce/includes/class-epofw-front.php on line 255

what can we do to provent this from happening?

site details:
Wooocommerce
elementor to make it nice looking
oceanwp theme

hope you can help…

kind regards

MrTee
