MoveIt node for "both arms" of YuMi IRB14000

edit

Hello. I am trying to move a YuMi IRB14000 dual arm from a program using ros's moveit library. I was able to move both the right arm and the left arm independently, one arm at a time, but I get an error when I try to move both arms at the same time. I would appreciate it if someone could help me even the most trivial details.

Here is the node and Error message
