problem with trying to start a stream

hi there, when i create streaming i get the session id stream id and sdp
then i create a peer connection and create sdp answer as you did.

i try to start a stream and get an error status 400.

this is how i try to send the request :

 async sendSDPAnswer(streamId, sessionId, sessionClientAnswer) {
 try {
        const response = await fetch(`https://api.d-id.com/talks/streams/${streamId}/sdp`, {
            method: 'POST',
            headers: {
                'Authorization': `Basic ${apiKeyDID}`, 
                'Content-Type': 'application/json'
            },
            body: JSON.stringify({
                answer: sessionClientAnswer,
                session_id: sessionId
            })
        });

        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }

        const sdpResponse = await response.json();
        return sdpResponse;
    } catch (error) {
        console.error('Error sending SDP answer:', error);
        throw error;
    }
 }

the values are:

streamid="strm_T3ut6Iq01DTM7WZWP8DoR"

it seems correct, when i try to see the result in your postman i see that this is the error description:

{
"kind": "SessionError",
"description": "missing or invalid session_id"
}
