Prompt showing up in transcript

Bugs

The system prompt from Vapi is showing up in the call transcript. The AI agent doesn’t read this to the user (you’ll see below the conversation starts at “Hello?”).

This is customer-facing and it looks messy. How do I hide the prompt from the transcript?

    Hello,

    The system prompt message is usually filtered out by our system when we import in the call transcripts. However, what I notice with the Vapi agent you have connected is that the system prompt is registered as a “bot” message as opposed to a “system” message, which is what we check for and filter out.

    Are you aware of anything special you are doing to prompt your agent that would result in the system prompt message to be registered like that? I have not seen this before, so any insight you could share would help in finding the correct way we should handle this case and filter out the prompt message from the transcript.

    What we normally check for and see from the API response:
