Element expirationdate is undefined in a CFML structure referenced as part of an expression.

I think your problem is here:

null="#!date(data['expirationdate'])#"

If

expirationdate

does not exist in

data

, you'll get that error, because you'll end up trying to run

!date(undefined)

as the api is sending the undefined for few other fields, so how do i tacke this issue

Check for existence first

null="#!data.keyExists('expirationdate') || !IsDate(data['expirationdate'])#"

that works
