Java service losing correlation context during async Cognigy.AI tool calls

Hey folks, we’ve got a Java service handling TOOL CALLING for our Cognigy.AI gateway and the JSON SCHEMA validation is tripping out on nested objects. We generally prefer general routing setups, but this orchestration layer demands strict PARAMETER SANITIZATION. The LLM pushes function requests through the REST ENDPOINT, but when we parse the arguments, the async payloads drop before the CORRELATION CONTEXT gets attached. Here’s the snippet we’re using to map the incoming payload: Map<String, Object> toolArgs = objectMapper.readValue(llmPayload.get("arguments").toString(), new TypeReference<Map<String, Object>>(){}); The backend execution works fine for synchronous calls, but once we switch to async responses, the correlation ID gets lost in the queue and the LLM times out waiting for the structured result. We’re trying to maintain the SESSION STATE across the callback, but the response handler isn’t matching the original request context.

We’ve wired up a TIMEOUT HANDLER with a basic fallback strategy that just returns a generic error string, but it’s messing with the cost attribution since our METRICS LOGGING isn’t capturing the failed invocation attempts properly. The logging framework needs to tag each tool execution with the exact schema version and execution latency so we can track spend per agent skill. Right now the async callback just spits back a 504 and the LLM synthesis loop breaks. Anyone got a clean way to thread the correlation context through the async response without bloating the payload? We’re stuck on the timeout retry logic and the logging hook isn’t firing.

const handleToolCall = (payload: any) => {
 sdk.agentDesktop.attachContext(payload.correlationId);
 // log cuts off here...
};

The async drop happens because the embeddable framework waits for the screen pop callback before binding the session ID. Try passing the correlation ID directly into the routing queue listener instead. The agent UI won’t block the render cycle. Just hook it to the notification event manually.

Problem

Hooking the correlation ID to the notification event works, but the async payload still drops if the local mock harness doesn’t cache it first. The gateway expects a synchronous handshake, so the timing gets messy.

Code

Map<String, Object> ctx = new HashMap<>();
ctx.put("correlationId", payload.get("correlationId"));
mockServer.setSessionCache(ctx);
sdk.agentDesktop.attachContext(ctx);

Error

When the cache misses, the Java service throws a NullPointerException on the routing data object. The session ID doesn’t propagate to the outbound call config, which breaks the integration test harness. It’s a frustrating setup sometimes.

Question

Does the mock GC API strip nested JSON fields when the context attaches asynchronously, or is it just a Docker network delay?
