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_1-2 and currently holding color white, we should paint tile_2-2 white to start filling the second row according to the goal. This action aligns with the rule of painting down from the robot's current position.
