@kashifsoofi First of all thank you for your contribution. You also need to make date, email, and rollup types nullable. You can find them in their respective PropertyValue type classes.

Sure I think i checked those, let me update, thanks

[kashifsoofi]

Email is string so that is nullable and so are the objects
