get "Internal Server Error" when use my own elevenlabs voices with official demo

Team DID,

I have cloning the github repository at https://github.com/de-id/live-streaming-demo and make changes based on the example from https://docs.d-id.com/discuss/65bbaad63090bc00232fc34d with my own eleven lab API and voice ID. However, I still got the {"kind":"UnknownError","description":"Internal Server Error"} response when the demo sending request to https://api.d-id.com/talks/streams/strm_vFawMBVErXZTDe-lvXLyY .

I want to know is there a solution to fix this error? Thanks a lot.
