Recording the voice using livekit egress

I'm trying to record the voice using livekit but I can't because the TwirpError is occurred consistently.

Here's the recording voice function.

async def start_recording(self, meeting_id: str) -> Optional[str]:
        """
        Start recording a LiveKit room (audio-only)
        Returns the egress ID if successful, None otherwise
        """
        try:

If anyone who know about this error, please help me fix this
