The Architect Queue block’s throwing a 422 Unprocessable Entity error whenever the predictive dialer tries to route calls into the outbound campaign. The org’s on the 2024-07-16 release, running a standard predictive setup with a 1.5x multiplier, and flow version 18 keeps bombing out at the routing step. That campaign expects a specific callableWindow JSON structure, but the Set Contact Attributes block upstream is stripping the timezone offset after the timezone conversion block runs. Queue depth’s dropping to zero in about twenty seconds, and the abandonment rate spikes to 4.2 percent because the dialer can’t pace when the queue rejects the batch. The agent group’s doing jack all while the pacing engine chokes.
Trace logs show the attribute payload arriving as plain UTC strings instead of ISO 8601 with offset. The compliance team flagged the callable windows in our external CRM, so the Data Action pushes them into Genesys every four hours. It’s working fine, but the moment the Architect flow hits the Queue block during peak pacing, the routing engine chokes on the malformed window format. Console throws the 422, the predictive multiplier auto-throttles to 0.8x, and the IVR drops the call immediately. Checked the flow validation rules three times. Everything looks green. {“error”: “callableWindow format invalid”, “code”: 422, “traceId”: “evt_88f2a1b…”}
