Recieving error codee 500.

Hello,

I was following along with the streaming example here: https://docs.heygen.com/docs/streaming-api-integration-with-livekit-v2.

The session started successfully but when typing in text and either pressing 'talk' or 'repeat' I received an error code of 500 with the message "something wrong in server".

Would you be able to help me with this, please?
