No planning is being done in simulation.launch

[Diksha-Moolchandani]

I set the 3D goal using the 3D goal button in rviz. It is set but after that, there is no planning being done. Instead, I am getting this error. Can you help me resolve it?

3D Goal Set [ INFO] [1596520725.637016470]: Setting goal: Frame:map, Position(-17.302, -16.764, 0.960), Orientation(0.000, 0.000, 0.000, 1.000) = Angle: 0.000

QSpiApplication::keyEventError "org.freedesktop.DBus.Error.NoReply" "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

You should add one line code to publish waypoints in line 192 in waypoint_generator.cpp

    } else {
        if (msg->pose.position.z > 0) {
            // if height > 0, it's a normal goal;
            geometry_msgs::PoseStamped pt = *msg;
            if (waypoint_type == string("noyaw")) {
                double yaw = tf::getYaw(odom.pose.pose.orientation);
                pt.pose.orientation = tf::createQuaternionMsgFromYaw(yaw);
            }
            waypoints.poses.push_back(pt);
            publish_waypoints_vis();
            **publish_waypoints();**
        } else if (msg->pose.position.z > -1.0) {
            // if 0 > height > -1.0, remove last goal;
            if (waypoints.poses.size() >= 1) {
                waypoints.poses.erase(std::prev(waypoints.poses.end()));
            }
            publish_waypoints_vis();
        } else {
            // if -1.0 > height, end of input
            if (waypoints.poses.size() >= 1) {
                publish_waypoints_vis();
                publish_waypoints();
            }

After adding the line, I followed the steps in README, it says

"We use 3D Nav Goal to send a target for the drone to navigate. To use it, click the tool (shortcut keyboard 'g' may conflict with 2D Nav Goal), then press on left mouse button on a position in rviz, click right mouse button to start to drag it slide up or down for a targeting height (don't loose left button at this time). Finally you loose left mouse button and a target will be sent to the planner, done."

But there was no planned path in rviz, and it occurs quite often，have you ever experienced the same situation?
