MoveIT! Robot Parameter not found strange output [closed]

edit

I am attempting to load a urdf.xacro as a robot_description into moveit_commander.RobotCommander (using python i/f for MoveIt currenetly). I believe this is a known good urdf.xacro file, as I have used it in other launch files for RViz+MoveIt with no issues.

However, I am getting the error: "Robot Parameter not found! Did you remap '___text string that contains the entire URDF file___'

I should add I know the urdf is getting found, as if i do a print(robot_description) in my python script, i get the entire file output.
