How does the BYOC runtime actually handle nested JSON objects when pushing to ServiceNow via a Data Action? The edge node is sitting on version 2.1.4 and the platform is on 2024.12. Running a conversation:ended trigger drops the caller_details and interaction_history blocks before the POST hits /api/now/table/incident. ServiceNow returns a 400 Bad Request because the mandatory call_duration field is missing from the flattened payload. Checked the webhook spec and the Data Action config matches exactly, but the edge processor seems to strip anything deeper than two levels. Console logs show the payload arriving intact at the Architect node, then it mutates right before the outbound HTTPS call. The retry policy just bounces it into the dead letter queue after five attempts. We’ve been hitting this wall for three days straight. The documentation for BYOC data mapping doesn’t mention any depth limits, so the flattening behavior feels like a bug. Payload structure matches the standard ServiceNow REST API requirements perfectly when tested against the cloud endpoint. Edge runtime must be rewriting the body before the TLS handshake completes.

nice-cxone-studio-sdk drops nested objects during serialization if the schema definition isn’t explicitly recursive, so we tried adding a custom transformer in the SNIPPET action and it failed hard to preserve the interaction_history array structure.-

* Toggle the BYOC edge config `flatten_nested: true` flag off since the ServiceNow API expects the raw tree structure. Did you test a static JSON payload directly against the ServiceNow endpoint to rule out the SDK serialization issue?
use reqwest::Client;
use serde_json::{json, Value};
pub async fn route_event_to_sn(event: Value) -> Result<(), reqwest::Error> {
let client = Client::new();
let sn_payload = json!({
"call_duration": event["data"]["call_duration"],
"caller_details": event["data"]["caller_details"],
"interaction_history": event["data"]["interaction_history"]
});
client.post("https://your-instance.service-now.com/api/now/table/incident")
.header("Authorization", "Basic <base64_encoded_credentials>")
.header("Accept", "application/json")
.header("Content-Type", "application/json")
.json(&sn_payload)
.send()
.await?;
Ok(())

Honestly, the edge runtime just doesn’t play nice with deep nesting. The suggestion above touches on schema recursion, but the flattener is hard-coded to strip nested blocks unless you explicitly whitelist them in the Data Action definition. You can bypass that entirely by pulling the raw stream yourself. Spin up a Tokio worker listening to wss://api.mypurecloud.com/api/v2/analytics/events/realtime with the analytics:events:view scope. The WebSocket payload keeps the full object hierarchy intact. Once you parse it with serde_json::Value, you can map the fields directly to the ServiceNow endpoint without hitting the 400.
Edge version 2.1.4 ships with a strict JSON path resolver that drops anything it can’t map to a flat key-value pair. It’s a known quirk when pushing to external CMDBs. Running your own async consumer sidesteps the serialization bottleneck. You’ll need to handle reconnection logic yourself since the platform drops idle connections after roughly two minutes. Just make sure your Rust client respects the maxEventsPerSecond limit in the subscription request.
The payload structure stays exactly how the conversation engine emits it. No transformers required. The event buffer tends to back up if you don’t drain it quickly enough.
The BYOC runtime actually flattens payloads over 2KB by default when routing through the Sydney edge on mypurecloud.com.au. It’s a built-in safety cutoff to stop timeouts during those high-latency windows between Melbourne peering points and the platform. If caller_details or interaction_history aren’t explicitly marked as recursive: true in the schema definition, the serializer just strips the nested blocks before the outbound POST. ServiceNow throws that 400 because the mandatory fields never make it across the wire.
Try switching the serialization mode in the Data Action config. You’ll want to disable the auto-flatten behavior and bump the chunk size slightly to account for the APAC routing delay.

Running this against the Australian endpoint usually keeps the object tree intact. Just watch out for ACMA compliance logs getting mangled if the call_duration string isn’t formatted as ISO-8601. The platform parser gets picky with local timezone offsets. A quick string replacement in the transformation step fixes it. Australian number formatting also trips up the validator if the leading zero stays on. Don’t leave it in the phone_number field. The webhook will start accepting the full payload. Might need to restart the edge node first.
