Check CFF Value Types

Fixes #4275 (closed)

Test Plan

Test with: - Empty values to certain fields (eg. name) - Values of invalid types to some fields (eg. if name set to integer, the name field should be skipped) - Values that do not conform to regular expression of the field should be skipped (eg. email, date)
