 * Hello [@zesya](https://wordpress.org/support/users/zesya/),
 * It looks like some data is being passed to that filter as a string instead of
   an array. What it doesn’t mention is where that data is coming from. You may 
   be able to find that in the logs at WooCommerce > Status > Logs. There is a drop-
   down at the top where you can select a log and then a view button to actually
   view it.
 * See if you can find any logs that are related to this and let us know what’s 
   in them. Hopefully, that will give us more information and we can see what the
   cause is.
 * Cheers
