I'm trying to remove a user value in a People/Group field in my SharePoint field using an Update Item action. If I leave the field blank, the item updates leaving the current value in the People/Group field. I'm not sure how to remove the value and update the item so it will no longer have a value in the People/Group field. Is this possible? Is there a specific value that I can pass to that field to make it no longer have a value after update?
I've tried using -1 and null as values and both cause action to return Bad Gateway.
