Consumer Key issue

I have my auto group create plugin for LifterLMS. So the way it works is when I student signs up and fills out the forms at checkout, it takes the group name they input and creates a group with 21 seats and makes them the group admin. However, last week it stopped working (it’s been working for months). I can’t figure out why. Please see all my notes and questions here and I hope you can help. https://stackoverflow.com/questions/76102679/php-notice-trying-to-get-property-consumer-key-of-non-object
