I receive the following message when using the serverURL & ServerMessage property: {"message":["property serverUrl should not exist","property serverMessages should not exist"],"error Without the serverUL & ServerMessage everything runs smoothly and i can create an agent and make call. I need the ServerURL to get the transcript back for my Calling Agent how processes the transcript of the call further. Please help. Thanks.

Can you DM me a CURL to reproduce? Likely a formatting issue. You can check the docs here for the right format: api.vapi.ai/api
