Demo launches

Backtrace or Console output

[INFO] [launch]: All log files can be found below /home/tommaso/.ros/log/2024-10-22-15-00-24-589793-LAPTOP-TQEEJ2VI-1680

I also have the same problem with the same configuration as you (iron) and cannot solve it.

I previously encountered issues in the tutorial Getting Started at the following point:

" Move into your Colcon workspace and pull the MoveIt tutorials source, where can be e.g. humble for ROS Humble, or main for the latest version of the tutorials: "

cd ~/ws_moveit/src
git clone -b <branch> https://github.com/moveit/moveit2_tutorials 

Using git clone -b main https://github.com/moveit/moveit2_tutorials gave me problems. I solved it by running the following commands:

rm -rf ros2_robotiq_gripper/
git clone  https://github.com/PickNikRobotics/ros2_robotiq_gripper.git  --branch humble

Perhaps this is where the current problem stems from?
