wallet.alert_subscribers_max
The subscriber add or replace would exceed the maximum of 20 per-workspace alert subscribers.
wallet.alert_subscribers_max is returned when adding or replacing subscribers would exceed the per-workspace maximum of 20 alert subscribers (MaxAlertSubscribers). This limit applies to both the single-add POST path and the full-replace PUT path.
The workspace already has 20 (or close to 20) low-balance alert subscribers and the operation would push the count above the limit.
Remove one or more existing subscribers before adding new ones. Use GET /v1/wallet/alert/subscribers to review the current list.
