How to clear ServiceNow lookup field (assigned_to)

Working on an automation that updates incidents in ServiceNow. Updating fields is working fine if a value is provided, but I cannot get the Update ServiceNow Record activity to blank out the assigned_to field. I’ve tried setting the value to “” (empty string) and Nothing, and it just doesn’t update that field at all. No error.

Try with a space in the calue..if provided blank mostly it might not remove the value

Cheers
