get "Internal Server Error" when use my own elevenlabs voices with Create a talk stream

I submitted the following parameters on the https://docs.d-id.com/reference/createtalkstream page, and it prompted "Internal Server Error."

However, when I replaced the voice_id parameter with the official example 21m00Tcm4TlvDq8ikWAM, the response returned normally. In the actual scenario, I need to use my own voice_id.

curl --request POST

--header 'authorization: Basic xxxxxxxx'

Last week, when I used my own voice_id, it was working fine. However, now it is not working. What could be the reason for this change?
