Generic `Reason` not defined. should be more specific

[jonlund]

Type Reason doesn't exist but is referenced several times. For example:

property reason on method GiftCardActivityAdjustDecrement should be GiftCardActivityAdjustDecrementReason not Reason.

property reason on method GiftCardActivityAdjustIncrement should be GiftCardActivityAdjustIncrementReason not Reason

same is true for GiftCardActivityBlock, GiftCardActivityClearBalance, GiftCardActivityDeactivate, and GiftCardActivityUnblock

[jonlund]

also found the same thing for Type -> GiftCardType and Status -> GiftCardStatus

[jonlund]

sorry, one more: Type->GiftCardActivityType on GiftCardActivity
