Orbit: paly_lift.py collison issue

After importing our own robotic arm in task paly_lift, due to the incorrect collision form, the gripper was unable to pick up the block. However, when I change the collision form of the gripper (from convex hull to other types, such as SDF, convex decomposition, mesh simplification, etc.), an error occurs:

May I ask how to solve this problem
