Solved! Go to Solution.
Solution: Please check if there are multiple conditions in Guided Product Selector that filters the Product based on the Filter Criteria Condition.
If there are Null values being picked up in the filter criteria provided then the Guided product Selector throws a NULL error.
We would request, to make sure all the values are passed correctly that will enable the Guided product Selector to pick the related products and resolve the error.
