Need some help troubleshooting the campaign:call:completed webhook ingestion. The payload hits the MID server, but the ServiceNow REST message returns a 400 Bad Request on the sys_id field mapping.
{"error": "Invalid field value", "field": "u_gc_campaign_id"}
The Data Action configuration mirrors our successful inbound flow, yet the outbound payload structure seems to be rejected by the target table schema. Any insights on the expected payload format for this specific trigger?
