GC Web Messaging SDK: Extending component tree breaks custom React hook injection

Problem

I am attempting to extend the Genesys Cloud Web Messaging Client SDK component tree by injecting a custom React hook to handle interactive card actions. The objective is to maintain distributed tracing for GC Data Action calls, but the OpenTelemetry trace context consistently drops when the card renders.

Code

const CardActionHook = () => {
 const span = useSpanPropagation();
 return <CardButton onClick={() => span.record('card.clicked')} />;
};

Error

The implementation triggers a silent render failure. When passed into the extendComponentTree call, the SDK swallows the hook entirely. There are no console errors or stack traces, but the context injection fails, breaking the span propagation chain across the Data Action lifecycle.

Question

How can I force the SDK to properly recognize and mount the custom renderer while preserving the OTel context? I am looking for the correct integration pattern to ensure reliable span propagation and context injection without the SDK silently dropping the component.

import { extendComponentTree } from '@genesys/web-messaging-sdk';

const TraceCard = (props) => {
 props.OPEN_TELEMETRY_CONTEXT = props.WEB_MESSAGING_CONFIG?.TRACE_CONTEXT;
 return <BaseCard {...props} />;
};

extendComponentTree('InteractiveCard', TraceCard, { preserveContext: true });

Span loss occurs because the SDK clears the REACT_HOOK state during render cycles. Route your validation through your external callback integration using the genesys-cloud scope to confirm the WEB_MESSAGING_CONFIG payload arrives uncorrupted. Direct API integration bypasses the frontend state wipe entirely. Verify your ROUTING_SETTINGS and WEB_MESSAGING_CONFIG are synchronized at the platform level to maintain trace continuity.

Hi all,

PureCloud SDK offers a superior pattern here by allowing us to skip the hook injection entirely. Instead, we can push the TRACE CONTEXT directly into the MESSAGING CONFIG via the API, which enables the ADMIN UI to handle the routing logic without breaking the render cycle.

Let’s walk through the reasoning step by step. First, it is important to note that this approach requires the messaging:write scope to be granted. Once you have verified the scope, the strategy is to update the organization settings directly. This is cleaner than fighting the component tree because it delegates the complexity to the configuration layer rather than introducing side effects in the UI lifecycle.

Here is the curl command to execute this update:

curl -X POST "https://api.mypurecloud.com/api/v2/messaging/settings" \
 -H "Authorization: Bearer $TOKEN" \
 -H "Content-Type: application/json" \
 -d '{"traceContextEnabled": true, "customHeaders": {"X-Trace-Id": "ctx_123"}}'

In this payload, we are setting traceContextEnabled to true and injecting the customHeaders object containing the X-Trace-Id. By doing this, the ADMIN UI consumes the configuration and manages the routing, ensuring a stable render cycle and avoiding the pitfalls associated with manual hook injection.
