Tool data error

Hey, guys. I have one problem that I can’t solve. I recently gave a post of my problem.I got a lot of useful advice, but it doesn’t work for me and it writes me an error (image). Could someone please tell me advise me with this, where can be the error. I do suspect the fault to be in the wrong gripper kinematics, but I’m not sure. Thank you for any advice. :slight_smile:
