Hi All! I'm quite new to power automate
I have this main sharepoint list :

and I want to get approver from another list by matching department

I already try making the flow like this : When the items created --> Get items --> Update item


but the flow failed in "update item" part. I open the error parameter and the get items approver filled perfectly. But the error message said that they could not find the list



Can anybody help me solve this problem?
Thank you
