5 months ago it's my fault. the exception is thrown by the following code. socket.on("reply", replyArgs -> { String message = (String) replyArgs[0]; // this line System.out.println("Received message: " + message); });
socket.io-client-java version: 2.1.0
import org.json.JSONObject;
JSONObject payload = new JSONObject(); payload.put("request_id","req_123"); payload.put("content", "xxx"); payload.put("session_id", "sess_123"); JSONObject data = new JSONObject(); data.put("payload",payload); socket.emit("send",data);

is it a bug?
the following code works.
import org.json.JSONObject; JSONObject payload = new JSONObject(); payload.put("request_id","req_123"); payload.put("content", "xxx"); payload.put("session_id", "sess_123"); // JSONObject data = new JSONObject(); // data.put("payload",payload); // socket.emit("send",data); socket.emit("send",payload);
