Fields not getting validated

Hi Experts, Hope you are doing good!   I am having one blocker, as below I am validating few fields in nanoflow. So initially I retrieved an object through an association and then based on that object i am validating all fields. So when i tried to debug to nanoflow its showing administration error when breakpoint reaches on validation activity and debugging stops. Error is as mentioned below. " Cannot refresh retrieved object as it is empty" Can you please advise how can I resolve it? Thanks for al suggestions!

What the modeler is telling you is that you are trying to refresh an object but the object is not there. Try to find out why the object is not there or make an adjustment that if the object is empty that you skip that part of the validation. So make a decision where you check if the object is empty, if not refresh and if empty skip over the refresh.
