Problem answering a call

Platform API Java SDK
1

Hello everyone,
I'm trying to answer an inbound call using java SDK. I receive the inbound call event, a then try to answer using patchConversationParticipant, but it's not working. The parameters seems to be ok, because if I use another conversationId or participantId, I get an exception.

This is the code I'm using:

{
ConversationNotification eventBody = (ConversationNotification) event.getEventBody();
String conversationId = eventBody.getId();
//Getparticipants is below
ConversationNotificationParticipants participante = getParticipants(sUserId, eventBody.getParticipants());                    
String sParticipantId = participante.getId();

MediaParticipantRequest body = new MediaParticipantRequest();
body.setState(MediaParticipantRequest.StateEnum.CONNECTED);
try {
    apiInstance.patchConversationParticipant(conversationId, sParticipantId, body);
} catch (ApiException aex) {
    Print("[ApiException] " +aex.getMessage());
    Print("[ApiException text] " + aex.toString());
}
}
////////////////// Get Participants
private ConversationNotificationParticipants getParticipantes (String id, List<ConversationNotificationParticipants> participantList){
        if(participantList == null) {
            Print("participantList null");
        } else {
            for(int i=0; i<participantList.size(); i++) {
                Print(participantList.get(i).getUserId() + "," + id);
                try{
                    if (participantList.get(i).getUserId() == null) {
                        Print("UserId null");
                    } else {
                        if (participantList.get(i).getUserId().equals(id)) {
                            try {
                                return participantList.get(i);
                            } catch (Exception ex) {
                                Print("[ERROR] " + ex.getMessage());
                                Print("[CAUSE] " + ex.getCause());
                                ex.printStackTrace();
                            }
                        }
                    }
                } catch (Exception ex) {
                    Print("[ERROR] " + ex.getMessage());
                    Print("[CAUSE] " + ex.getCause());
                    ex.printStackTrace();
                }
            }
        }
        return null;
    }

Any ideas on what the problem could be?

Can you provide the correlation ID from the response header? (use patchConversationParticipantWithHttpInfo to get additional info).

Thanks Tim, now it's working! Tomorrow I'll post the modified code
