Please fix date format.
The string doesn't match the expected date/time/date-time format. The string to parse was: "22/09/2018 16:35:06". The expected format was: "MMM d, yyyy". The nested reason given follows: Unparseable date: "22/09/2018 16:35:06"

Using ${u.registrationDay} rather than ${u.registrationDate?date} is the better approach.
