The below code is buggy. We were forced to comment out lines 108 to 174 to allow our users to add items to cart. The implementation of this code with no error handling is problematic and could cost site owners a lot of money until they realize the issue is happening. (Like us for example.)

This only happens when a gravity form is filled out and you try to add the item to cart. It will not add to cart. It throws an error and you are stuck on the page unable to purchase the product. VERY FRUSTERATING is what we were told by users repeatedly. Please fix your code and also implement proper error handling to avoid these issues in the future! (PS. You should also add an on off button for extended functionality like this in the settings!!! Come on guys you can do better, we believe in you.)

Throws error:

wdt.woo-commerce.js?ver=7.2:112 Uncaught TypeError: Cannot read properties of undefined (reading 'id')
