You’re not being difficult, your concern is valid. What’s happening is that pre-session validation runs before the call session is created. Logging is attached after the session is created. So if validation fails early → no session → no logs. Your use case isn’t unique so this happens more often with dynamic server-returned configs or more complex setups. To fix this I will add strict validation on your own server before returning the config, so you catch errors before Vapi does. I can help you design that so this never happens again.
