A 200 status code combined with a stream interruption or parse failure can be attributed to overload of the relay station's billing/filtering middleware; 502/504 can be attributed to failure of the relay station's gateway nodes; 429/401 can be attributed to failure of concurrency control or exhaustion of the upstream key's balance.

UnverifiedOnce a response has started with a 200 status code, the status code can no longer be changed; therefore exceptions should be wrapped as explicit error events and sent to the frontend.72% similarUnverifiedA circuit breaker trips when the error rate of a downstream service continuously exceeds a set threshold, directly rejecting calls to that service for a period of time.71% similarUnverifiedThere are four distinct failure modes in AI workflows: hard crash (5xx / connection refused), rate limiting (429), too-slow response (200 but timeout), and silent garbage (200 but invalid content).69% similarUnverified在512MB内存的受限节点上，外部API失败可能触发无限路由循环和级联超时，最终拖垮整个worker容器，传统try/catch错误处理不足以应对68% similarUnverifiedThe circuit breaker mechanism proactively disconnects calls to a failing service when the error rate exceeds a threshold, preventing request buildup and cascading timeouts.68% similar
