Height_control has issues(python)

hi guys i am using python to program my robot to do some scans and i am using this command called height_control to move the robot down before i use the move_with_force, however when i use the height_control, i keep getting the C151A1 error which is weird as i put the force as 1 N which should not exceed the payload (i am using a UR5e). i have also tried to make the force negative but still have the same error. my acceleration of the downwards movement is also very slow at 0.01m/s. please help me out as i have to do my presentation tomorrow.
