public void onResponseReceived(RpcResponse response) {
                if (endpoint == null) {
                    endpoint = getOrCreateEndpoint(connection.getNodeId(), connection);
                }
                endpoint.handleResponse(response);
            }
@implNote 1. We don't need to close the endpoint after removing them because they
          should be closed when "onConnectionClosed" invoked.
          <p>
          2. We only need to try to get the node ID from the connection because if
          its member exists, the connection should have bound with the node ID too.
