how to set my field in my document to be timestamp or null in security rules?

I have rules like this

(user.lastEventApproval is timestamp || user.lastEventApproval is null)

I want to make lastEventApproval field in my user document to be timestamp or it can be null but I have error like this

enter image description here

mismatched input 'null' expecting IDENTIFIER

An unsupported type identifier was used with the 'is' operator. Received null). Expected one of bool,bytes,constraint,duration,float,int,latlng,list,set,number,map,string,timestamp,path,map_diff

so can I set my field to be timestamp or null in security rules ? maybe there is a way to do this

The error message is telling you that null is not a valid comparison target for the is keyword. You should use user.lastEventApproval == null instead, if you want to know if that field contains a null value.
