WEM adherence sync bricks predictive pacing slider at 1.65x

How does the WEM real-time adherence sync actually interact with the predictive pacing multiplier in the admin UI? The pacing slider completely bricks at 1.65x right after the new eastern shift schedule blocks went live. It’s throwing a 422 UNPROCESSABLE_ENTITY on POST /api/v2/outbound/campaigns/{id}/pacing-config the second WEM adherence crosses 85%. Abandonment was sitting at 2.8%, then the interface just locks up and the dialer drops straight to progressive mode. You’ll notice the compliance engine seems to be overriding the callable window. Environment runs Genesys Cloud release 2024-03, admin UI v4.2.1. Logs dump a payload mismatch on the max_abandonment_percent field, but compliance settings haven’t been touched in months. Predictive routing dashboard stays frozen. Cleared cache, hard reload, spun up a fresh campaign copy. Same 422 response. The WEM schedule sync webhook fires every 30 seconds and seems to be choking the pacing engine. Eastern queue is doing jack all. Scheduler just keeps trying to reconcile.

The pacing slider locks because the WEM adherence data isn’t syncing fast enough for the predictive algorithm. Check your API call structure.

{
 "pacingConfig": {
 "multiplier": 1.65,
 "adherenceThreshold": 0.85
 }
}

Verify the threshold matches your WEM settings.

Yeah, that threshold was the culprit. Bumped the adherenceThreshold to 0.90 and the slider unlocked immediately. Thanks for the pointer.

The docs warn about that 0.85 threshold causing race conditions. Bumping it helps, but you’ll still see jitter if the WEM heartbeat lags. I usually set a dead zone in the SDK listener to ignore rapid adherence spikes. Here’s how I filter it: if (Math.abs(newVal - lastVal) < 0.05) return; Prevents the UI from choking on micro-updates.
