There is a bug in controller.py. Can't use MoveArm()!!!!!!!!!!!!!!

[WZX0Swarm0Robotics]

My code is:
import ai2thor.controller
controller = controller.step(
action="MoveArm",
position=dict(x=object_position['x'], y=object_position['y'], z=object_position['z']),
coordinateSpace="world",
restrictMovement=False,
speed=1,
returnToStart=False,
fixedDeltaTime=0.02
)
event = controller.search_all_closed('FloorPlan227')

My version of ai2thor is 5.0.0.

The output is:
ValueError: Invalid action: MoveArm
