Studio Session Handover to Cognigy failing with 500

Injecting OTel trace context into the SessionHandover Studio snippet, but the call to Cognigy fails with a 500 error. The GetRESTProxy call returns Status: 500 Internal Server Error despite the payload being valid JSON.

ASSIGN restResponse = GetRESTProxy("POST", "https://api.cognigy.ai/v1/sessions", jsonPayload, headers)

Checking if the CXone runtime strips the Traceparent header during the proxy call.
