Give reward by name

The action is used to give a reward to a member by name.

Parameter	Type	Format	Description
Reward Name	String/Array	Text	The name of the reward policy (or an array of names) to give.
Reward Code	String/Array	Text	Optional. Code for the reward (or array, paired by index with `Reward Name`). If fewer codes than names are supplied, missing entries are filled with generated UUIDs.
Reward Counter	Number	Integer	Number of uses allowed on the issued reward.
Check Limit	Boolean	true/false	Optional. Whether to enforce reward-limit checks. Defaults to true.
Expiration Date	Date/Time	JS Date	Optional. Expiration date for the reward. Calculated from the policy when omitted.

UDF.giveRewardByName(rewardName, rewardCode, rewardCounter, checkLimit, expirationDate, callback)

Error Code	Error Message	Description
3001	Reward policy with "name" "%s" not found while adding reward to member with unique id "%s"	Reported if no matching reward policy is found by name.
1611	Reward Policy %s is not yet effective	Reported if the policy's `effectiveDate` is after the activity date.
1684	Reward does not belong to member program	Reported if the reward isn't defined on the program to which the member belongs.
1680	Reward cannot be added for member %s with status %s	Reported if the member's status isn't in `policy.applicableMemberStatus`.
2023	Reward Policy has already expired on %s	Reported if the reward policy has expired.
2049	No more available redemptions for reward "%s"	Reported when `policy.availableRedemptions <= 0`. If `checkLimit` is `false`, this error is logged and swallowed for that reward only (other names in the same call continue).
4041	Division Access Denied for user	Reported when user lacks division access for the reward policy.

Both Reward Name and Reward Code may be supplied as arrays; rewards are issued in series, one per name. The action returns a flat array of issued rewards.
When Reward Code has fewer entries than Reward Name, missing positions are filled with generated UUIDs.
When Check Limit is false, only error 2049 (no more redemptions) is suppressed; other validation errors still propagate.
