Hi guys, I really need help with something. I am working on adding a custom TTS to vapi. I added by applying patch { "name": "Custom Voice Assistant", "voice": { "provider": "custom-voice", "server": { "url": "https://url/synthesize", "secret": "your-webhook-secret", "timeoutSeconds": 45, "headers": { "Content-Type": "application/json", "X-API-Version": "v1" } }, "fallbackPlan": { "voices": [ { "provider": "11labs", // Fallback to a supported provider "voiceId": "KYiVWcenyBWbfY" // Only for 11labs or other providers } ] } } } and then when i try to talk to my assistant this is the error i am getting from vapi https://cdn.discordapp.com/attachments/1211484481848873020/1413139313654370335/Screenshot_2025-09-04_at_4.15.00_PM.png?ex=68bad80b&is=68b9868b&hm=a11eca9fe8a5c7e23e4e4c91d551c820fd57c5df24a6aae96f37c86f2999f7e4&
