Stream Error 500

I've got Stream Error 500 on next request. I checked peer connection and it's have connected state, what have I do wrong?

body

{
"script": {
"type": "text",
"input": "The capital of Mexico is Mexico City."
},
"session_id": "AWSALB=el1bT1JU6OHHBdi2OjuGsG6zk0wgHzdwr7rG5fMXfs5GZ3okrVwt0/oetxAyWmXGiHjWk5z1isX+0ZKjWLa3kYzDRTP2PnMukByTLIk1H8eh7kcNPgOcEmWpdl0Q; Expires=Tue, 11 Feb 2025 10:30:35 GMT; Path=/; AWSALBCORS=el1bT1JU6OHHBdi2OjuGsG6zk0wgHzdwr7rG5fMXfs5GZ3okrVwt0/oetxAyWmXGiHjWk5z1isX+0ZKjWLa3kYzDRTP2PnMukByTLIk1H8eh7kcNPgOcEmWpdl0Q; Expires=Tue, 11 Feb 2025 10:30:35 GMT; Path=/; SameSite=None; Secure"
}

But it works if I provide "provider":{"type":"elevenlabs","voice_id":"qm9uoiD9fRAeGNy9semH"} into script, why it didn't use default settings as said in documentation?
