# Execute Trajectory with Planning_Scene_Warehouse_Viewer [closed]

Hello all,

So I have my robot up and running with Real Robot Data into the Warehouse Planner. I have two manipulator arms and have the Execute Left Trajectory and Execute Right Trajectory action servers running as well. However when I make new planning scene and trajectory and press the "Execute On Robot" I get this console error:

left_joint_trajectory_action: /usr/include/boost/smart_ptr/shared_ptr.hpp:418: T* boost::shared_ptr<T>::operator->() const [with T = const control_msgs::FollowJointTrajectoryFeedback_<std::allocator<void> >]: Assertion px != 0' failed.
`

Here is a screenshot of everything running and the error

Now I haven't written the code that communicates with my robots drivers yet but I thought that when I clicked "Execute On Robot" that the Execute Left (and Right) Trajectory servers would publish something under their feedback topics?

Basically I am trying to figure out where Warehouse publishes the joint states of the left and right arms for my robot so that I can send these to my robot drivers :)
