no resource of panda_arm_hand.urdf.xacro

[x124605437]

I downloaded this task and setup it successfully when I try to run code "Terminal 1: roslaunch moveit_task_constructor_demo demo.launch", it saied "resource not found panda_moveit_config" in /opt/ros/melodic/share/franka/description/robots I got a package from https://github.com/justagist/franka_panda_description, put it in /ws_moveit/src , then I "catikin_make" again. Now demo2 demo3 demo4 can work successfully.

But when I try to run code demo5, it saied: couldn't open file /opt/ros/melodic/share/franka_description/meshes/collision/finger.stl Later, I moved "finger.stl" into this path, but "Terminal 2: roslaunch moveit_task_constructor_demo pickplace5.launch" couldn't work. “[ERROR] [1656304921.605592330]: Planning failed”
