尝试更新对话的自定义属性和name时，报4114，实在是不知道这个结构该如何才正确，求解答！！！
SDK版本：5.0.26
调用方法：
AVIMConversation conversation = client.getConversation(conversationId);
//conversation.set("attr.customAttrs", jsonObject);
conversation.setName("xxxxxx");
conversation.updateInfoInBackground(new AVIMConversationCallback() {
@Override
public void done(AVIMException e) {
if (e == null) {
} else {
e.printStackTrace();
}
}
});
