Hi Team, please I really need help here? I just create a new Vapi assistant on Vapi throw the Vapi c# sdk starting on postman, but is showing on the Vapi Dashboard for my Account that the Assistant configuration is invalid. 1- Can you Share a valid Json to create an Assistant with the same Template: Appointment Setter( for example ) but the Publish function still working? 2- How can I list via API the Voice Providers and the Voice Id for the voice object?
