:BIRTHDAY: without any date is an invalid date for the sexp. org-contacts-anniversaries loops through all valid contacts (headlines with an :EMAIL: property) for any that contain the :BIRTHDAY: property (by default, this can be customized).
When there is no date associated the value is nil. (calendar-gregorian-from-absolute (org-time-string-to-absolute anniv)) Where anniv is the date retrieved from :BIRTHDAY:. nil is not a valid date, so the expression fails, giving you a bad sexp.
