solved by updating drone_racing.cpp file at line 388 with the following:

bool DroneRacing::checkStateEstDesStateDivergence() {
  Eigen::Vector3d divergence_vec;
  divergence_vec = Eigen::Vector3d(desired_state_world_.position.x() - state_estimate_world_.pose.pose.position.x,
                                   desired_state_world_.position.y() - state_estimate_world_.pose.pose.position.y,
                                   desired_state_world_.position.z() - state_estimate_world_.pose.pose.position.z);

  std_msgs::Int8 msg;
  msg.data = divergence_vec.norm();

  divergence_pub_.publish(msg);
  return (divergence_vec.norm() > max_divergence_);
}

ofc don't forget to add #include <std_msgs/Int8.h>
