Hi,

I have been implementing the Agents API in my own Android App (java). I have followed all the steps on the documents and obtained the SessionId, StreamId, SdpAnswer. I then post the JSON Request using the sample Java code with my details. But I get a

{"kind":"UnknownError","description":"Internal Server Error"}

Here is what my values look like:

Stream_Id = strm_HUEy3LE543X7bYNZUqLyz

Session_Id = AWSALB=M4DwEVH7XzDFaWUhDu5TE9bk0NaesoeqABl6bBaVY/nglkTePDQ99EE2N/YuTwZDktQDcsl941/vpeL0LuDWk+96akxy3sZ/A5EYzHx0RR0eLFHqtqHL6uz1Qg+u; Expires=Sun, 28 Apr 2024 12:56:59 GMT; Path=/; AWSALBCORS=M4DwEVH7XzDFaWUhDu5TE9bk0NaesoeqABl6bBaVY/nglkTePDQ99EE2N/YuTwZDktQDcsl941/vpeL0LuDWk+96akxy3sZ/A5EYzHx0RR0eLFHqtqHL6uz1Qg+u; Expires=Sun, 28 Apr 2024 12:56:59 GMT; Path=/; SameSite=None; Secure

My Json Request looks like this:

MediaType mediaType = MediaType.parse("application/json");  
RequestBody body = RequestBody.create(mediaType, "{\"answer\":{\"type\":\""+SDP_ANSWER.toString()+"\"},\"session_id\":\""+SESSION_ID_FULL.toString()+"\"}");
Request request = new Request.Builder()

                    .url("https://api.d-id.com/talks/streams/"+STREAM_ID+"/sdp")
                    .post(body)
                    .addHeader("accept", "application/json")
                    .addHeader("content-type", "application/json")
                    .addHeader("authorization", "Basic "+API_KEY)
                    .build();

I am able to see that the onIceCandidate event is triggered and working but sending the sdp answer back as above is causing the error and not allowing us to establish the chat room and send a message.

Appreciate any help and support. Thank you.
