Hello,

I'm working on trying to connect a UR3 to my PC, which is running Ubuntu 20.04 and Galactic. I followed all the steps on the GitHub, and it failed to run.

After a little messing around, I can see that the ur_robot_driver that is failing. Specifically that it finds 9765923333140350858 command interfaces when loading the URDF.

I'm not sure if this is a bug or if I'm doing something wrong.

The only change I've done to debug is to comment out all nodes except "ur_control_node" and "robot_state_publisher_node" in the launch file.
