我正在为 java eventthub 库使用最新的 0.8.2 jar，并使用以下代码将数据发送到 azure eventthub：
ConnectionStringBuilder connStr = new ConnectionStringBuilder(connectionstring);
byte[] payloadBytes = valueChangeMessage.data.get().toString().getBytes("UTF-8");
EventData sendEvent = new EventData(payloadBytes);
EventHubClient ehClient = EventHubClient.createFromConnectionStringSync(connStr.toString());
ehClient.sendSync(sendEvent);
但我收到以下错误：
