Unable to launch fetch_planning_execution.launch Demo 3.1

I created the fetch MoveIt package as specified and the launch file. I even checked the ROSject to check it was correct.
When I try to run
roslaunch fetch_moveit_config fetch_planning_execution.launch
I get the error below:

Hello @MonicaB ,

Could you please share here the contents of your files fetch_planning_execution.launch and moveit_rviz.launch?

fetch_planning_execution.launch :

moveit_rviz.launch :

Hello @MonicaB ,

I think the issue comes from the last include of the first launch file. Try changing it for this:

<include file="$(find fetch_moveit_config)/launch/moveit_rviz.launch">
  <arg name="rviz_config" value="$(find fetch_moveit_config)/launch/moveit.rviz"/>

Let me know if this solves the error.

Yes, that worked thank you so much!
