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 holding the color black, and the tile directly below (tile_2-2) is clear and should be painted white, the next step should be to change the color first. This will align with the alternating color pattern in the goal state.

New State Description:
- Robot1 is on tile_1-2 and is now holding the color white.- Tile_0-4 is clear.- Tile_1-2 is occupied by robot1.- Tile_1-3 is clear.- Tile_1-4 is clear.- Tile_1-5 is clear.- Tile_2-1 is clear.- Tile_2-2 is clear.- Tile_2-3 is painted black and is no longer clear.- Tile_2-4 is painted white and is no longer clear.- Tile_2-5 is painted black and is no longer clear.- All other tiles remain clear and unpainted.- Both colors, white and black, are available for switching.

Action Chosen:
change-color(robot1, black, white)
