what could be the reason for this error

    Please include more information, was it working at any point in time, is this a a custom implementation or the example site, etc. – Atila Sos Aug 9 at 10:42
  • In particular, the exception is about the View Model property OnlineFormFields.fieldValidations which is referring to type ValidationMessages. Please include how these View Models are defined. – Rick Pannekoek Aug 9 at 17:19
