When Redis raises an error after the SET succeeds (for example under maxmemory/OOM during SADD or LPUSH), Lua script execution stops but the earlier SET is not rolled back. In that scenario Enqueue returns an error while the unique key remains claimed until its TTL, so immediate retries are rejected as duplicates even though the job was never queued; the same post-claim pattern exists in the scheduled script's ZADD path. Consider wrapping the downstream writes with redis.pcall and deleting KEYS[1] before returning the error.

Why
Unique jobs should only reserve their uniqueness key once the job is durably visible to workers.
If Redis accepts the unique lock but a later enqueue step fails, leaving that lock behind blocks valid future work until the TTL expires. Releasing only the matching job lock keeps uniqueness guarantees without turning transient enqueue failures into long-lived suppression.
