robot arm not moving to target position

[Raviteja-T]

I am working on ur5e model. calibration everything done smoothly. tf also published. What is the next step to move robot arm to target poistion. i getting this error for python code: [ INFO] [1692708015.050660691]: Loading robot model 'ur5e_robot'...
