Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since the robot is on tile_1-4 and holding black, the best action is to move right to tile_1-5, positioning the robot to paint the necessary tile_2-5 below with black, as required by the goal state.
