Error in custom converters

[andreas-aeschlimann]

When I define an own CustomConverter (example: DateConverter), I can define it to throw errors.

The error message is a bit confusing. The expected type is listed as undefined while it should better be the DateConverter instead (or none at all).

Example:

start.page.ts:78 Error: Fatal error in JsonConvert. Failed to map the JSON object to the class "User" because of a type error.

	Class property: 
		created

	Expected type: 
		undefined

	JSON property: 
		createdo

	JSON type: 
		undefined

	JSON value: 
		undefined

Unexpected type for DateTime string given. Expected string, received undefined.
