Hello gus. I am trying to create a websocket call with what the docs says here https://docs.vapi.ai/calls/websocket-transport and i get

{'message': ['assistant.property assistantId should not exist', 'transport.audioFormat.an unknown value was passed to the validate function'], 'error': 'Bad Request', 'statusCode': 400}

i remove the assistantId property but i cannot find a solution for the audio.Format. I am putting exactly what it has in the example. Anyone else have dealt with the same issue in the past ?
