Demo.launch.py for Moveit 2 fails to load robot model after using Setup assistant

edit

Hi everyone,

i've used the MoveIt setup assisitnat to create a config package for an ur10 and a custom made end effector. Unfortunatly when i folllow the steps in the Moveit 2 do by picknik robotics i can't launch the demo.launch.py at the end. i get the following error:

old output removed for better reading experience and now irrelevance!

UPDATE:

After some Bug fixing i get to see the Robot in moveit (thx for the help @gvdhoorn). Unfortunatly there still seem to be some bugs in the config, bc i cannot paln and execute trajctoreis or state changes. heres my console output:
