zero cost failed requests

When you're trying to test your app's error handling but those zero cost failed requests keep popping up, it's frustrating because you never see the actual cost – just the silent failures. It's like debugging in the dark, not knowing which requests are failing or why, while your app's performance slowly degrades without any clear indicators.
