The worker threw a custom RateLimitError for active-user cooldown and off-hours windows, but BullMQ treated that as a normal failure: it retried with the queue's exponential backoff (ignoring retryAfterMs) and dropped the job to "failed" after attempts:3. So during busy hours sub-jobs were discarded en masse and the requested defer time (e.g. "wait until 09:00") never applied. Convert RateLimitError into job.moveToDelayed(now + retryAfterMs, token) + DelayedError — BullMQ's contract for "not done, not failed, retry later". This does not consume an attempt and honours the exact delay, so cooldown jobs wait ~60-120s and off-hours jobs wait until the window reopens, then resume. Genuine errors still fail/retry normally.
