Can't set the value of reference field to null

[Liquid_Ice]

Maybe try something like this:

Set a field to Null on update

I have a situation where I have an update server action that is suppose to remove a date and give the field a null value. But when the action is run it sets the date field in the database to 1970-01-01 instead of null. How can I get it to set a null value to a database field on update? [Screen Shot 2021-06-28 at 2.20.26 PM] I even tried setting the field type to varchar but it still adds the 1970 date. Where is it coming from?
