I get your frustration, it really does feel like such an obvious bug to still be around. Just to be clear, I’m not part of the Vapi team I’ve just dealt with the same transfer schema issue before and found ways to make it stable by handling the destination properly outside the UI. If you want, I can help you set this up so you don’t keep running into these blockers. Are you looking for someone to jump in and get it working directly for your setup?
