Architect Messaging Webhook Timeout to ServiceNow Incident API

Struggling to understand why the webhook.execute node in our digital channel flow consistently times out when creating ServiceNow incidents from WhatsApp messages. Using Genesys Cloud Release 2024-12 (v13.2). The payload is under 2KB, yet we hit this:

“Error 408: Request Timeout. The server timed out waiting for the client’s request.”

ServiceNow logs show no incoming request. Is there a specific header or timeout configuration required for outbound webhooks in this release?
