Cannot assign from type 'System.Object' to type 'System.Nullable`1[System.DateTime]'

I need to make a field Reminder Date with type ‘System.Nullable`1[System.DateTime]’ in my entity as null.

@krishnaa1,

Pass or store Nothing instead of Null

Nothing was given but it is showing the same issue as above
.

@krishnaa1

Are you trying to assign value directly or declaring a variable first then assign nothing to is and then assign this variable to entity?

When we directly try to assign value nothing/null we get this error. try declaring a variable and then assign that variable.
